Narrated Abu Wail:
حَدَّثَنَا إِسْحَاقُ ، أَخْبَرَنَا النَّضْرُ ، حَدَّثَنَا شُعْبَةُ ، عَنْ سُلَيْمَانَ ، قَالَ سَمِعْتُ أَبَا وَائِلٍ ، عَنْ حُذَيْفَةَ ، {وَأَنْفِقُوا فِي سَبِيلِ اللَّهِ وَلاَ تُلْقُوا بِأَيْدِيكُمْ إِلَى التَّهْلُكَةِ} قَالَ نَزَلَتْ فِي النَّفَقَةِ.
Hudhaifa said, "The Verse:-- "And spend (of your wealth) in the Cause of Allah and do not throw yourselves in destruction," (2.195) was revealed concerning spending in Allah's Cause (i.e. Jihad).
