2636. Narrated 'Umar bin Al-Khaṭṭāb رَضِيَ اللَّهُ عَنْهُ: Once I gave a horse (for riding) in Allāh's Cause. Later, I saw it being sold. I asked Allāh's Messenger ﷺ (whether I could buy it). He said, "Don't buy it, for you should not get back what you have given in charity." bedouin came to the Prophet ﷺ and asked him about emigration. The Prophet ﷺ said to him, "May Allāh be Merciful to you. The matter of emigration is difficult. Have you got some camels?" He replied in the affirmative. The Prophet ﷺ asked him, "Do you pay their Zakāt?" He replied in the affirmative. He asked, "Do you lend (give) some of them to others (as gratis) so that their milk may be utilized by others?" The bedouin said, "Yes." The Prophet ﷺ asked, "Do you milk them on the day of watering them?" He replied, "Yes." The Prophet ﷺ said, "Do good deeds beyond the merchants (or the sea) and Allāh will never disregard any of your deeds." (See Hadīth No.3923, Vol.5)
