أَبُو الْوَقَّاصِ، عَنْ زَيْدِ بْنِ أَرْقَمَ
The Prophet ﷺ said: When a man makes a promise to his brother with the intention of fulfilling it and does not do so, and does not come at the appointed time, he is guilty of no sin. (Using translation from Abū Dāʾūd 4995)
عَنِ النَّبِيِّ ﷺ قَالَ «إِذَا وَعَدَ الرَّجُلُ أَخَاهُ وَمِنْ نِيَّتِهِ أَنْ يَفِيَ لَهُ وَلَمْ يَجِئْ لِلْمِيعَادِ فَلَا إِثْمَ عَلَيْهِ»
