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 [proper] for the people of Madīnah and those surrounding them of the bedouins that they remain behind after [the departure of] the Messenger of Allāh or that they prefer themselves over his self.¹ That is because they are not afflicted by thirst or fatigue or hunger in the cause of Allāh, nor do they tread on any ground that enrages the disbelievers, nor do they inflict upon an enemy any infliction but that it is registered for them as a righteous deed. Indeed, Allāh does not allow to be lost the reward of the doers of good.
