"Whenever a (Muslim) person dies, and a group of Muslims numbering one hundred pray janazah for him, all interceding on his behalf, their intercession is granted (by Allah) and he is forgiven."
Muslim and others
Ibn 'Abbas, rahimahullah, reported that Allah's Messenger, sallallahu 'alayhi wa sallam, said:
"Whenever a Muslim man dies, and forty men stand for his janazah prayer, all of them not joining anything with Allah in worship, Allah grants them intercession for him."
Muslim and others
Maymunah, rahimahullah, reported that Allah's Messenger, sallallahu 'alayhi wa sallam, said:
"Whenever a (Muslim) person dies, and a group of (Muslim) people pray janazah for him, they are granted intercession for him."
An-Nisa'i, verified hasan by Al-Albani, Sahih al-Jami'. no. 5787
Malik ibn Hubayrah, rahimahullah, reported that Allah's Messenger, sallallahu 'alayhi wa sallam, said:
"Whenever a Muslim dies, and three lines of Muslims pray janazah for him, he is granted forgiveness."
Ahmad, Abu Dawud, and others,
verified hasan by Al-Hafidh and others; Al-Albani disagrees with this because Muhammad ibn Ishaq one of the narrators is known to be a mudallis (one who is ambiguous in stating his sources) and did not declare direct hearing of this report (Ahkam ul-Jana'iz, 128). Yet the Prophet's, sallalaahu 'alayhi wa sallam, practice of forming three lines for janazah prayer provides a further supporting evidence for this hadith).
