At-Tawbah 9:120 ما كان لاهل المدينة ومن حولهم من الاعراب ان يتخلفوا عن رسول الله ولا يرغبوا بانفسهم عن نفسه ذالك بانهم لا يصيبهم ظما ولا نصب ولا مخمصة في سبيل الله ولا يطيون موطيا يغيظ الكفار ولا ينالون من عدو نيلا الا كتب لهم به عمل صالح ان الله لا يضيع اجر المحسنين ١٢٠

It was not becoming of the people of Al-Madinah and the bedouins of the neighbourhood to remain behind Allâh’s Messenger (Muhammad صلى الله عليه وسلم when fighting in Allâh’s Cause) and (it was not becoming of them) to prefer their own lives to his life. That is because they suffer neither thirst nor fatigue, nor hunger in the Cause of Allâh, nor they take any step to raise the anger of disbelievers nor inflict any injury upon an enemy but is written to their credit as a deed of righteousness. Surely, Allâh wastes not the reward of the Muhsinûn ¹
