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.”]

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.”
