صحیح مسلم #125
حَدَّثَنَا أَبُو الطَّاهِرِ وَحَرْمَلَةُ بْنُ يَحْيَی وَأَحْمَدُ بْنُ عِيسَی قَالَ أَحْمَدُ حَدَّثَنَا و قَالَ الْآخَرَانِ أَخْبَرَنَا ابْنُ وَهْبٍ قَالَ أَخْبَرَنِي يُونُسُ عَنْ ابْنِ شِهَابٍ قَالَ حَدَّثَنِي سَعِيدُ بْنُ الْمُسَيَّبِ أَنَّ أَبَا هُرَيْرَةَ أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّی يَقُولُوا لَا إِلَهَ إِلَّا اللَّهُ فَمَنْ قَالَ لَا إِلَهَ إِلَّا اللَّهُ عَصَمَ مِنِّي مَالَهُ وَنَفْسَهُ إِلَّا بِحَقِّهِ وَحِسَابُهُ عَلَی اللَّهِ
It is narrated on the authority of Abu Huraira that when the Messenger of Allah ( صلی اللہ علیہ وسلم ) breathed his last and Abu Bakr was appointed as his successor (Caliph), those amongst the Arabs who wanted to become apostates became apostates. 'Umar b. Khattab said to Abu Bakr: Why would you fight against the people, when the Messenger of Allah declared: I have been directed to fight against people so long as they do not say: There is no god but Allah, and he who professed it was granted full protection of his property and life on my behalf except for a right? His (other) affairs rest with Allah. Upon this Abu Bakr said: By Allah, I would definitely fight against him who severed prayer from Zakat, for it is the obligation upon the rich. By Allah, I would fight against them even to secure the cord (used for hobbling the feet of a camel) which they used to give to the Messenger of Allah (as zakat) but now they have withheld it. Umar b. Khattab remarked: By Allah, I found nothing but the fact that Allah had opened the heart of Abu Bakr for (perceiving the justification of) fighting (against those who refused to pay Zakat) and I fully recognized that the (stand of Abu Bakr) was right.
