Sayyiduna Nu'man bin Bashir (may Allah be pleased with them both) said that Sayyiduna Abdullah bin Rawahah (may Allah be pleased with him) fainted, and his sister began to weep, saying: "Alas, my mountain!" and she was enumerating such qualities. When he regained consciousness, he said: Whatever you said about me, it was said to me: "Are you really like that?"
Imam Bukhari (may Allah have mercy on him) recorded it in his Sahih from Imran bin Maysarah (may Allah have mercy on him), who narrated it from Ibn Fudayl (may Allah have mercy on him); and Abthar (may Allah have mercy on him) narrated it from Husayn (may Allah have mercy on him) and added that when he died, she (his sister) did not weep over him.
