حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ إِسْمَاعِيلَ قَالَ سَمِعْتُ قَيْسَ بْنَ أَبِي حَازِمٍ قَالَ قَالَ سَعْدٌ لَقَدْ رَأَيْتُنِي مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ سَابِعَ سَبْعَةٍ وَمَا لَنَا طَعَامٌ إِلَّا وَرَقَ الْحُبْلَةِ حَتَّى إِنَّ أَحَدَنَا لَيَضَعُ كَمَا تَضَعُ الشَّاةُ مَا يُخَالِطُهُ شَيْءٌ ثُمَّ أَصْبَحَتْ بَنُو أَسَدٍ يُعَزِّرُونِي عَلَى الْإِسْلَامِ لَقَدْ خَسِرْتُ إِذَنْ وَضَلَّ سَعْيِي
مسند امام احمد بن حنبل · Hadith 1498
It was narrated that Isma'eel said: I heard Qais bin Abi Hazim say: Saad said: I was one of the first seven to embrace Islam with the Messenger of Allah (PBUH) and we had no food except the leaves of al-hublah (a desert tree), and one of us would produce stools like a sheep, so dry that nothing stuck to it. And now Banu Asad are teaching me about my religion, in which case I must have been doomed and my efforts wasted.
