حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ: حَدَّثَنَا سُفْيَانُ، عَنْ أَيُّوبَ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: ”لَيْسَ لَنَا مَثَلُ السَّوْءِ، الْعَائِدُ فِي هِبَتِهِ، كَالْكَلْبِ يَرْجِعُ فِي قَيْئِهِ.“
It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings of Allah be upon him) said: "An evil example does not befit us (Muslims). The one who takes back a gift after giving it is like a dog that vomits and then licks it up itself."
