Whoever sees that promises should be fulfilled

وَفَعَلَهُ الْحَسَنُ، وَذَكَرَ إِسْمَاعِيلَ إِنَّهُ كَانَ صَادِقَ الْوَعْدِ. وَقَضَى ابْنُ الأَشْوَعِ بِالْوَعْدِ. وَذَكَرَ ذَلِكَ عَنْ سَمُرَةَ. وَقَالَ الْمِسْوَرُ بْنُ مَخْرَمَةَ سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، وَذَكَرَ صِهْرًا لَهُ قَالَ: «وَعَدَنِي فَوَفَى لِي». قَالَ أَبُو عَبْدِ اللَّهِ وَرَأَيْتُ إِسْحَاقَ بْنَ إِبْرَاهِيمَ يَحْتَجُّ بِحَدِيثِ ابْنِ أَشْوَعَ.Al-Hasan supported this judgement. (Allah says:) "And mention in the Book (the Qur'an) Isma'il (Ishmael): Verily! He was true to what he promised." (V.19:54) Ibn Al-Ashwa' judged that promises should be fulfilled, and he mentioned that Samura adopted the same opinion. Narrated Al-Miswar bin Makhzama رضي الله عنه: I heard the Prophet ﷺ saying: (about one of his sons-in-law), "He promised me and fulfilled his promise." Narrated Abu 'Abdullah (Al-Bukhari): I saw Ishaq bin Ibrahim depending on Ibn Ashwa's narration in giving verdicts.
