All of the ahādīth of congratulating for Ramaḍān are all weak: Nothing is
authentic concerning it

❌ 5. “There has come to you Ramaḍān, a blessed month, the fasting of which Allāh has obligated upon you. In it, the gates of Paradise are opened, the gates of Hell are closed, and the devils are chained up.
In it there is a night which is better than a thousand months; whoever is deprived of its goodness is indeed deprived.”

[ ☑️ The confirmed report: “When the month of Ramadan begins, the gates of mercy are opened, the gates of Jahannam are closed and the devils are chained up.”]

❌ 6. On the last day of Shaˋbān, the Messenger of Allāh صلى الله عليه وسلم addressed us and said: “O people! A great month is coming to you. A blessed month. In it, there is a night that is better than a thousand months. Allāh Has obligated its fasting and made it voluntary to pray its nights. Whoever draws nearer to Allāh by performing any of the voluntary good deeds in this month shall receive the same reward as there is for performing an obligatory deed at any other time. And whoever performs an obligatory deed in it shall receive the reward of performing seventy obligations at any other time. And it is the month of patience, and the reward for patience is Paradise. And it is the month of equality. And it is a month in which a believer’s provisions are increased. Whoever gives food to a fasting person to break his fast, it will be like he freed a slave and he will have his sins forgiven.” It was said: “O Messenger of Allāh, not all of us possess the means whereupon we can give a fasting person [provisions] to break his fast.” He said: “Allāh gives the same reward to the one who gives a fasting person [provisions] to break the fast, a sip of milk, a date, or a drink of water. And whoever feeds a person who was fasting until he is full, it will be a cause for his sins to be forgiven, and Allāh will give him a drink from my Ḥawḍ [cistern], after which he will not be thirsty until he enters Paradise. And he will have the same reward as him [i.e. the fasting person] without his reward being diminished at all. And it is a month; the beginning of which is mercy, the middle of which is forgiveness and the end of which is emancipation from the Fire. And whoever lessens the burden of his bondsmen in it [i.e. this month], Allāh will free him from the Fire.”


❌ 7. “Count the (the appearance of)the crescent of Sha’ban for Ramaḍān.”

[☑️ The confirmed report: “Do not precede the month of Ramaḍān by a day nor by two days.”]

Pre-Ramadan declutter (things to clear out)

The aḥādīth of remembrance and supplication when seeing the new moon of Ramaḍān: There is nothing authentic concerning it

❌ 8. That the when Prophet صلى الله عليه وسلم would see the new moon, he would say:
“O Allāh, Bring it over us with blessing, faith, security and Islām. My Lord and your Lord is Allāh (Allāhumma ahlilhu `alaynā bil-yumni wal-īmān was-salāmati wal-Islām: Rabbī wa Rabbuka Allāh).


❌ 9. The Prophet صلى الله عليه وسلم used to say, when Rajab began: “O Allāh, bless for us Rajab and Shaˋbān and bless for us Ramaḍān.” And he used to say: “Friday night is honourable and its day is luminous.”


❌ 10. ‘If the middle of Shaˋbān comes, then do not fast.'

The Week Before Ramadhān
| Shaykh Ahmad Jibril

“The week before Ramadhān is the most crucial week probably... the Shaytān is gonna be shackled... You know what he’s gonna do in this week? When someone’s going to jail and he’s bad, he’s gonna do all the worst things he can imagine, before he goes.”
— Shaykh AMJ


Before Ramadhān comes, do your best to repent from all sins, clean your heart from all grudges towards Muslims, end all disputes and arguments with people, and cut off from everything that will distract you and take away from your focus and worship in the precious moments of Ramadhān. Purify yourself and your surroundings now, so that you can enter Ramadhān in a high and good state of īmān, and reap its rewards and blessings more than ever, in shā Allāh.

Sufficing with the testimony of one person in seeing the new moon: There is nothing authentic concerning it

❌ 11. “The people looked for the new moon, so I informed the Messenger of Allāh ﷺ that I had sighted it. So, he fasted and commanded the people to fast.”


❌ 12. “A Bedouin man came to the Prophet صلى الله عليه وسلم and said: ‘O Messenger of Allāh, I have seen the new moon tonight.’ He said: ‘Do you bear witness that none has the right to be worshipped but Allāh and that Muḥammad is the Messenger of Allāh?’ He said: ‘Yes.’ He said: ‘O Bilal, announce to the people that they should fast tomorrow.’”


"And what is correct is that it is not accepted except by the sighting of two just people. And this is what is confirmed from the Prophet صلى الله عليه وسلم."

________
Opinion of Shaykh al-Muhaddith Sulayman al 'Alwān

Shaykh al 'Alwān, however is of the opinion that it is enough if one just man sees the new moon, and what is looked at is his truthfulness and justness. This is based on the hadith of Ibn 'Umar which was narrated by Abū Dawūd. When he witnessed the moon, he reported the news to Prophet ﷺ and Prophet ﷺ commanded others to fast. Shaykh 'Alwān considers the chain of this narration to be strong. He also mentions that there are a group of scholars who say that two witnesses are needed instead of one, and that they take as dalīl the hadith of 'Abur-Rahmān ibn Zayd ibn Khattāb which says: "So if two witnesses witness, fast and break the fast." In its chain is al-Hajjāj ibn Artā who is weak (Daīf), and every other chain of this Hadīth without the mention of al-Hajjāj is wrong and weak. Indeed there is no doubt that two witnesses are needed to end every month and to begin the rest. The only exception for this is Ramaḍān for which only one witness is enough. For the rest of the months, however, without a doubt two witnesses are needed.

Our Note:

We have mentioned the opinion of two scholars of Hadīth regarding the strength of narration in Abū Dawūd and their respective opinions on whether one or two witnesses suffice for the sighting of the moon for Ramadān.

Shaykh Abū Alī does not consider it to be Sahīh (rather he says it is Munkar) and that two witnesses are needed, while Shaykh al 'Alwān says the chain is strong and Ramadān moon sighting is the exception to the rule that two witnesses are needed (one is enough for Ramadān). This is absolutely fine for scholars to have some differences of opinion [we stated both to clarify]

Ahamdulillahi (Added by KnowYourRabb)

The fast is the day the people fast, the breaking of the fast is the day the people break their fast, and the sacrifice is the day the people sacrifice: There is nothing authentic concerning it

❌ 13. “The fast is the day the people fast, the breaking of the fast is the day the people break their fast, and the sacrifice is the day the people sacrifice.” (Tirmidhī) & ‘The breaking of the fast is the day the people break their fast, and the sacrifice is the day the people sacrifice.' (Ibn Mājah)
