A similar tradition has also been transmitted by Ibn 'Abbas though a different chain of narrators. This version says:

"He (the Prophet) purchased a calf from a caravan, but he had no money with him. He then sold it with some profit and gave the profit in charity to the poor and widows of Banu 'Abd al-Muttalib. He then said: I shall not buy anything after this but only when I have money with me.

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، عَنْ شَرِيكٍ، عَنْ سِمَاكٍ، عَنْ عِكْرِمَةَ، رَفَعَهُ - قَالَ عُثْمَانُ وَحَدَّثَنَا وَكِيعٌ، عَنْ شَرِيكٍ، عَنْ سِمَاكٍ، عَنْ عِكْرِمَةَ، - عَنِ ابْنِ عَبَّاسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم مِثْلَهُ قَالَ اشْتَرَى مِنْ عِيرٍ تَبِيعًا وَلَيْسَ عِنْدَهُ ثَمَنُهُ فَأُرْبِحَ فِيهِ فَبَاعَهُ فَتَصَدَّقَ بِالرِّبْحِ عَلَى أَرَامِلِ بَنِي عَبْدِ الْمُطَّلِبِ وَقَالَ لاَ أَشْتَرِي بَعْدَهَا شَيْئًا إِلاَّ وَعِنْدِي ثَمَنُهُ ‏.‏
