Hadith 20:622
Sa'b bin Jaththamah (May Allah be pleased with him) reported:
I presented a wild ass to Messenger of Allah (ﷺ) as a gift but he returned it to me. When he perceived signs of despair on my face, he said, "I have declined to accept it because I am in the state of Ihram." [Al-Bukhari and Muslim] .
وعن الصعب بن جثامة رضي الله عنه قال: أهديت رسول الله صلى الله عليه وسلم حماراً وحشياً فرده علي، فلما رأى ما في وجهي قال: “إنا لم نرده عليك إلا لأنا حرم” ((متفق عليه))
