عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ قَالَ إِنَّ اللَّهَ نَظَرَ فِي قُلُوبِ الْعِبَادِ فَوَجَدَ قَلْبَ مُحَمَّدٍ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ خَيْرَ قُلُوبِ الْعِبَادِ فَاصْطَفَاهُ لِنَفْسِهِ فَابْتَعَثَهُ بِرِسَالَتِهِ ثُمَّ نَظَرَ فِي قُلُوبِ الْعِبَادِ بَعْدَ قَلْبِ مُحَمَّدٍ فَوَجَدَ قُلُوبَ أَصْحَابِهِ خَيْرَ قُلُوبِ الْعِبَادِ فَجَعَلَهُمْ وُزَرَاءَ نَبِيِّهِ يُقَاتِلُونَ عَلَى دِينِهِ فَمَا رَأَى الْمُسْلِمُونَ حَسَنًا فَهُوَ عِنْدَ اللَّهِ حَسَنٌ وَمَا رَأَوْا سَيِّئًا فَهُوَ عِنْدَ اللَّهِ سَيِّئٌ
Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: Allah Almighty looked upon the hearts of His servants and found the heart of Muhammad (peace and blessings be upon him) to be the best among all human hearts, so He chose Muhammad (peace and blessings be upon him) for Himself and sent him with the message of Prophethood. Then, after selecting this heart, He looked upon the hearts of the rest of the servants and found the hearts of the companions of Muhammad (peace and blessings be upon him) to be the best among all human hearts, so He made them the ministers (and companions) of His Prophet, who fight for His religion. Thus, whatever the Muslims consider good is also good in the sight of Allah, and whatever the Muslims consider bad is also bad in the sight of Allah. 1
