Sayyiduna Samurah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) used to forbid a man to remain unmarried, and (he forbade) that he be deprived of entering the houses of the believers.
Imam al-Tabarani recorded this narration; I found this narration thus in the copy from which I transcribed it, and its chain is hasan (good). The hadith narrated from Sayyiduna Sa'id bin al-As (may Allah be pleased with him) has already passed.
