Sahih Muslim 1876
Sahih Muslim · Book 33: The Book on Government · The virtue of Jihad and going out (to fight) in the cause of Allah
Another version of the tradition narrated through a different chain of transmitters on the authority of Abu Huraira has the same wording as the previous tradition:
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ ، حَدَّثَنَا جَرِيرٌ ، عَنْ سُهَيْلٍ ، عَنْ أَبِيهِ ، عَنْ أَبِي هُرَيْرَةَ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " تَضَمَّنَ اللَّهُ لِمَنْ خَرَجَ فِي سَبِيلِهِ - إِلَى قَوْلِهِ - مَا تَخَلَّفْتُ خِلاَفَ سَرِيَّةٍ تَغْزُو فِي سَبِيلِ اللَّهِ تَعَالَى " .
" Allah takes care of one who goes out in the way of Allah" but ends in the words:" I would not lag behind any expedition which is undertaken to fight in the way of Allah, the Exalted."
