2. Ali ibn Ibrahim has narrated from his father, from ‘ Abd Allah ibn al-Mughirah from Isma‘il ibn abu Ziyad who have said the following: “Abu ‘Abd Allah, has narrated from his ancestors, ‘Alayhim al-Salam, who have stated this Hadith. ‘Once, the Holy Prophet, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, asked his companions, ‘Should I tell you something which, if you do it, will keep Satan away from you as far as east and west?’ They replied, ‘Please do so.’ The Holy Prophet said, ‘Fasting turns Satan’s face black, charity breaks his back, love for the sake of Allah and supporting good deeds cuts off his tail (followers), and asking forgiveness cuts off his artery. Everything has a zakat (cleanser). Zakat of the bodies is fasting.’”

3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from ibn Faddal from Tha’labah from Ali ibn ‘Abd al-‘Aziz who has said the following: “Abu ‘Abd Allah (a.s.), once asked me, ‘Should I tell you what the root, the branch, the peak and the highest point of Islam is?’ I replied, ‘Please, do so.’ He said, ‘The root of Islam is salat (prayer), its branch is zakat, and its peak and highest point is al-Jihad in the way of Allah. Should I tell you about the doors to goodness? Fasting certainly is a shield.’”
