Ka'b b. Malik told that he said, “Messenger of God, to make my repentance complete* I should divest myself of my property as sadaqa for God and His Messenger.” God's Messenger replied, “Retain some of your property, for that will be better for you.” So he said he would retain the portion he had at Khaibar.
(Bukhari and Muslim.) This is part of a long tradition.
* Mirqat, iii, 566 refers this to his withdrawal from the expedition to Tabuk without a valid reason.
Pt. 10
Ibn ‘Abbas told that Sa'd b. ‘Ubada asked the Prophet for a decision about a vow taken by his mother who had died before fulfilling it, and that he gave decision that he should fulfil it on her behalf.
Anas said that the Prophet saw an old man being supported between his sons, and on asking what was the matter with him and being told that he had taken a vow to walk,* he said, “God most high has no need that this man should punish himself,” and he ordered him to ride. In a version by Muslim on Abu Huraira’s authority he said, “Ride, old man, for God is not in need of you and your vow.”
*Mirqat, iii, 565 explains this as a vow to walk to the Ka’ba.
