'Auf bin Malik Al-Ashja'i (May Allah be pleased with him) reported:
Seven, eight or nine people, including myself, were with Messenger of Allah ﷺ on an occasion when he ﷺ remarked, "Would you pledge allegiance to Messenger of Allah?" As we had taken oath of allegiance shortly before, we said, "We have already done so, O Messenger of Allah." He again asked, "Would you not pledge allegiance to Messenger of Allah?" So we stretched out our hands and said, "We have already made our pledge with you, O Messenger of Allah, on what should we make a pledge with you?" He said, "To worship Allah and not to associate anything with Him, to perform the five (daily) Salat and to obey." Then he added in a low tone, "And not to ask people for anything." Thereafter, I noticed that some of these people who were present did not ask anyone to pick up even the whip for them if it fell from their hands. [Muslim].
وعن أبي عبد الرحمن عوف بن مالك الأشجعي رضي الله عنه قال: كنا عند رسول الله ﷺ تسعة أو ثمانية أو سبعة فقال: "ألا تبايعون رسول الله ﷺ" وكنا حديثي عهد ببيعة، فقلنا: قد بايعناك يا رسول الله، فعلام نبايعك؟ قال: "على أن تعبدوا الله ولا تشركوا به شيئاً، والصلوات الخمس وتطيعوا" وأسر كلمة خفية: "ولا تسألوا الناس شيئاً" فلقد رأيت بعض أولئك النفر يسقط سوط أحدهم فما يسأل احداً يناوله اياه. ((رواه مسلم)).
