Praise be to Allah.
The hadeeth of Salman (may Allah be pleased with him) was narrated by Ibn Khuzaymah in his Saheeh. He said: Chapter on the virtues of the month of Ramadhan if the report is saheeh. Then he said: ‘Ali ibn Hijr al-Sa’di told us, Yoosuf ibn Ziyad told us, Humam ibn Yahya told us, from ‘Ali ibn Zayd ibn Jad’an, from Sa’eed ibn al-Musayyab, from Salman (may Allah be pleased with them) who said: The Messenger of Allah (peace and blessings of Allah be upon him) addressed us on the last day of Sha’ban and said: “O people, there has come to you a great month, a blessed month, a month in which there is a night that is better than a thousand months. Allah has made fasting it obligatory and spending its nights in prayer a voluntary act. Whoever draws close (to Allah) during it by doing a good deed will be like one who did an obligatory deed in any other month, and the one who does an obligatory deed in it will be like one who did seventy obligatory deeds in any other month. It is the month of patience, and the reward of patience is Paradise. It is the month of helping others. It is a month in which the believer’s provision is increased. Whoever gives a fasting person food with which to break his fast will have his sins forgiven and he will be ransomed from the Fire, and he will have a reward like his without it detracting from his reward in the slightest.” They said: Not all of us can find something to give to the fasting person with which to break his fast. He said: “Allah will give this reward to the one who gives a fasting person a date or a drink of water or a sip of milk. It is a month the beginning of which is mercy, the middle of which is forgiveness and the end of which is ransom from the Fire. The one who reduces the burden for his slave will be forgiven by Allah, and He will ransom him from the Fire. So do a lot of four good deeds during it, two with which you will please your Lord and two which you cannot do without. As for the two good deeds with which you will please your Lord, they are bearing witness that there is no god except Allah, and seeking His forgiveness. As for those which you cannot do without, they are asking Allah for Paradise and seeking refuge with Him from Hell. Whoever feeds a fasting person until he is full, Allah will give him to drink from my Cistern, a drink after which he will not thirst again until he enters Paradise.”
Its isnad (chain of narration) includes ‘Ali ibn Zayd ibn Jad’an, who is da’eef (weak) because of his bad memory. Its isnad also includes Yoosuf ibn Ziyad al-Basri, whose hadeeth is munkar (rejected). It also includes Humam ibn Yahya ibn Dinar al-‘Awadi, concerning whom Ibn Hajar said in al-Taqreeb: He is trustworthy but he may make mistakes.
Based on this, the hadeeth with this isnad is not false, but it is weak. However, many of the virtues of Ramadhan are proven in the saheeh ahadeeth (authentic narrations).
