Riyad as-Salihin 26
Abu Sa'id Al-Khudri (May Allah be pleased with him) reported that:
Certain people of the Ansar asked the Messenger of Allah (ﷺ) and he gave them; then they again asked him and he gave them until all what he possessed was exhausted. Then the Prophet (ﷺ) said, "Whatever wealth I have, I will not withhold from you. Whosoever would be chaste and modest; Allah will keep him chaste and modest and whosoever would seek self-sufficiency, Allah will make him self-sufficient; and whosoever would be patient, Allah will give him patience, and no one is granted a gift better and more comprehensive than patience". [Al-Bukhari and Muslim] .
وعن أبي سعيد سعد بن مالك بن سنان الخدري رضي الله عنهما‏:‏ ‏"‏أن ناساً من الأنصار سألوا رسول الله صلى الله عليه وسلم فأعطاهم، ثم سألوه فأعطاهم ، حتى نفد ما عنده، فقال لهم حين أنفق كل شيء بيده ‏:‏ ‏"‏ما يكن عندي من خير فلن أدخره عنكم ، ومن يستعفف يعفه الله، ومن يستغن يغنه الله، ومن يتصبر يصبره الله‏.‏ وما أعطي أحد عطاءً خيراً وأوسع من الصبر‏"‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏ ‏.‏
