Hadith 2:330
Narrated Ibn 'Umar (RA):
Allah's Messenger (ﷺ) said: "Pray (funeral prayers) over him who said (believed): 'Nothing deserves to be worshiped except Allah'; and pray behind him who says: 'Nothing deserves to be worshiped except Allah'." [ad-Daraqutni reported it through a weak chain of narrators].
