وعن طلحة بن عبيد الله
رضي الله عنه قال: جاء رجل إلى رسول الله صلى الله عليه وسلم، من أهل نجد، ثائر الرأس نسمع دوي صوته، ولا نفقه ما يقول، حتى دنا من رسول الله صلى الله عليه وسلم فإذا هو يسأل عن الإسلام، فقال الرسول صلى الله عليه وسلم: «خمس صلوات في اليوم والليلة«قال: هل علي غيرهن؟
قال: «لا، إلا أن تطوع«فقال رسول الله صلى الله عليه وسلم: «وصيام شهر رمضان«قال: هل على غيره؟ قال: «لا إلا أن تطوع«قال: وذكر له رسول الله صلى الله عليه وسلم، الزكاه فقال: هل علي غيرها؟
قال: «لا، إلا أن تطوع«فأدبر الرجل وهو يقول: والله لا أزيد على هذا ولا أنقص منه، فقال رسول الله صلى الله عليه وسلم: «أفلح إن صدق»
A person with dishevelled hair, one of the people of Najd, came to the Messenger of Allah (sallallahu alayhi wa sallam). We heard the humming of his voice but could not fully understand what he was saying, till he approached close to the Messenger of Allah (sallallahu alayhi wa sallam). Then I came to know that he was asking about Islam.
The Messenger of Allah (sallallahu alayhi wa sallam) said: “There are five (obligatory) Salat during the day and the night.” He said: “Am I obliged to perform any other (Salat) besides these?”
The Messenger of Allah (sallallahu alayhi wa sallam) said, “No, but whatever you observe voluntarily.” He (sallallahu alayhi wa sallam) added, “There is the Saum of Ramadan.”
The inquirer asked: “Am I obliged to do anything besides this?” The Messenger of Allah (sallallahu alayhi wa sallam) said, “No, but whatever you do out of your own free will. You may observe voluntary fasting.” And the Messenger of Allah (sallallahu alayhi wa sallam) told him about the Zakat (obligatory charity).
The inquirer asked: “Am I obliged to pay anything besides this?” The Messenger of Allah (sallallahu alayhi wa sallam) said, “No, but whatever you pay voluntarily out of your own free will.” That man turned back saying: “By Allah! I will neither make any addition to this nor will I decrease anything from it.” (Upon hearing this) the Messenger of Allah (sallallahu alayhi wa sallam) remarked, “He is successful if he proves truthful (to what he is saying).”.
