Sahih al-Bukhari 1489

Hadith text

Narrated `Abdullah bin `Umar:`Umar bin Al-Khattab gave a horse in charity in Allah's Cause and later he saw it being sold in the market and intended to purchase it. Then he went to the Prophet (ﷺ) and asked his permission. The Prophet said, "Do not take back what you have given in charity." For this reason, Ibn `Umar never purchased the things which he had given in charity, and in case he had purchased something (unknowingly) he would give it in charity again

Abdullah bin Umar (رضی اللہ عنہما) bataate hain: Umar bin Khattab ne Allah ki raah mein ek ghoda sadqa mein diya, aur baad mein use bazaar mein bikte dekha aur ise khareedne ka iraada kiya. Woh Nabi ke paas gaye aur ijazat maangi. Nabi ne farmaya: "Jo sadqa mein de chuke, use wapas mat lo." Isi wajah se Ibn Umar ne kabhi woh cheezein wapas nahi khareedi jo unhone sadqa mein di thi, aur agar (anjaane mein) kuch khareedte, use phir sadqa kar dete.
