Hadith 17015

حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ ، قَالَ : حَدَّثَنَا شُعْبَةُ ، عَنْ أَبِي الْفَيْضِ ، عَنْ سُلَيْمِ بْنِ عَامِرٍ ، قَالَ : كَانَ مُعَاوِيَةُ يَسِيرُ بِأَرْضِ الرُّومِ ، وَكَانَ بَيْنَهُمْ وَبَيْنَهُ أَمَدٌ ، فَأَرَادَ أَنْ يَدْنُوَ مِنْهُمْ ، فَإِذَا انْقَضَى الْأَمَدُ غَزَاهُمْ ، فَإِذَا شَيْخٌ عَلَى دَابَّةٍ يَقُولُ : اللَّهُ أَكْبَرُ ، اللَّهُ أَكْبَرُ ، وَفَاءٌ لَا غَدْرٌ ، إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قَالَ : " مَنْ كَانَ بَيْنَهُ وَبَيْنَ قَوْمٍ عَهْدٌ ، فَلَا يَحِلَّنَّ عُقْدَةً وَلَا يَشُدَّهَا حَتَّى يَنْقَضِيَ أَمَدُهَا ، أَوْ يَنْبِذَ إِلَيْهِمْ عَلَى سَوَاءٍ " ، فَبَلَغَ ذَلِكَ مُعَاوِيَةَ فَرَجَعَ ، وَإِذَا الشَّيْخُ عَمْرُو بْنُ عَبَسَةَ .
Saleem bin Aamir says that once Hazrat Ameer Muawiya (may Allah be pleased with him) set out with an army towards the land of Rome. There was still some time left in the agreement between Hazrat Muawiya (may Allah be pleased with him) and the Romans. Hazrat Muawiya (may Allah be pleased with him) thought that they would stop after getting close to them, and as soon as the term ended, they would start fighting them. But it was seen that an old man riding a mount was going along saying, "Allahu Akbar, Allahu Akbar! The promise should be fulfilled, the covenant should not be broken. The Prophet (peace and blessings of Allah be upon him) has said: 'If a person has an agreement with any nation, he should not untie or tie its knot before the term ends or before they break the covenant from their side.'" When Hazrat Muawiya (may Allah be pleased with him) came to know of this, he turned back, and it was found out that the old man was Hazrat Amr bin Abasah (may Allah be pleased with him).
