Al-Adab Al-Mufrad, Book 39, Hadith 9 (In-Book) ⓘ

'Abdullah ibn as-Sa'ib reported that in the year of al-Hudaybiyya, when 'Uthman ibn 'Affan told the Prophet, may Allah bless him and grant him peace, that Suhayl had been sent to him by his people to make a truce with them on the basis that, provided that he leave them this year, they would leave Makka empty for him for three days. When 'Uthman came and the Prophet, may Allah bless him and grant him peace, was told, "Suhayl has come," he said, "Allah has made our business easy (sahhala)."

حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ، عَنْ مَعْنِ بْنِ عِيسَى قَالَ‏:‏ حَدَّثَنِي عَبْدُ اللهِ بْنُ مُؤَمَّلٍ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللهِ بْنِ السَّائِبِ، أَنَّ النَّبِيَّ صلى الله عليه وسلم عَامَ الْحُدَيْبِيَةِ، حِينَ ذَكَرَ عُثْمَانُ بْنُ عَفَّانَ أَنَّ سُهَيْلاً قَدْ أَرْسَلَهُ إِلَيْهِ قَوْمُهُ، فَصَالَحُوهُ عَلَى أَنْ يَرْجِعَ عَنْهُمْ هَذَا الْعَامَ، وَيُخَلُّوهَا لَهُمْ قَابِلَ ثَلاَثَةٍ، فَقَالَ النَّبِيُّ صلى الله عليه وسلم حِينَ أَتَى فَقِيلَ‏:‏ أَتَى سُهَيْلٌ‏:‏ سَهَّلَ اللَّهُ أَمْرَكُمْ وَكَانَ عَبْدُ اللهِ بْنُ السَّائِبِ أَدْرَكَ النَّبِيَّ صلى الله عليه وسلم‏.‏
