Abu Dawud Book 33, Hadith Number 4380.

Narated By Safwan : AbuDawud said: Za’idah has also transmitted it from Simak from Ju’ayd ibn Hujayr. He said: Safwan slept. Mujahid and Tawus said: While he was sleeping a thief came and stole the cloak from beneath his head. The version of AbuSalamah ibn AbdurRahman has: He snatched it away from beneath his head and he awoke. He cried and he (the thief) was seized. Az-Zuhri narrated from Safwan ibn Abdullah. His version has: He slept in the mosque and used his cloak as pillow. A thief came and took his cloak. The thief was seized and brought to the Prophet (PBUH).
