Sunan Abi Dawud 24615
In-book no 4111حَدَّثَنَا مَحْمُودُ بْنُ خَالِدٍ، حَدَّثَنَا عُمَرُ، عَنِ الأَوْزَاعِيِّ، فِي هَذِهِ الْقِصَّةِ فَقِيلَ يَا رَسُولَ اللَّهِ إِنَّهُ إِذًا يَمُوتُ مِنَ الْجُوعِ فَأَذِنَ لَهُ أَنْ يَدْخُلَ فِي كُلِّ جُمُعَةٍ مَرَّتَيْنِ فَيَسْأَلَ ثُمَّ يَرْجِعَ .
The tradition mentioned above has also been transmitted by al-Auza'i through a different chain of narrators. This version adds: He was told: Messenger of Allah, in that case he will of starvation. So he allowed him to visit (the cit) twice a week so that he might ask for food and go back.
