Sayyiduna Abu Qatadah (may Allah be pleased with him) said: "Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) went out looking for the Messenger of Allah (peace and blessings be upon him) but did not find him (peace and blessings be upon him). Then he looked for him in his houses, but did not find him there either, so he followed his trail from one street to the next until he was directed to him (peace and blessings be upon him) on Mount Thawab. So he went out and climbed Mount Thawab, looked right and left, and caught sight of him (peace and blessings be upon him) in the cave which people had made into a path to Masjid al-Fath, and he (peace and blessings be upon him) was in prostration. (Sayyiduna Mu'adh (may Allah be pleased with him) said:) I came down from the top of the mountain while he (peace and blessings be upon him) was still in prostration. He (peace and blessings be upon him) did not raise his head, until I began to fear the worst about him (peace and blessings be upon him) and thought that his soul had been taken. When he (peace and blessings be upon him) raised his head, I said: 'O Messenger of Allah, I feared the worst about you and thought that your soul had been taken.' He (peace and blessings be upon him) said: 'Jibril (peace be upon him) came to me in this very place and said: "Allah, the Blessed and Exalted, sends you greetings of peace and says: What would you like Me to do with your Ummah?" I said: "Allah knows best." He went away, then came back to me and said: "He says: I will not grieve you concerning your Ummah." So I fell into prostration; and the best of the means by which nearness to Allah is sought is prostration.'"
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) only with this chain; Ibrahim bin al-Mundhir is alone in narrating it."
