﴿ مَا كَانَ لِأَهْلِ ٱلْمَدِينَةِ وَمَنْ حَوْلَهُم مِّنَ ٱلْأَعْرَابِ أَن يَتَخَلَّفُوا۟ عَن رَّسُولِ ٱللَّهِ وَلَا يَرْغَبُوا۟ بِأَنفُسِهِمْ عَن نَّفْسِهِۦ ۚ ذَٰلِكَ بِأَنَّهُمْ لَا يُصِيبُهُمْ ظَمَأٌۭ وَلَا نَصَبٌۭ وَلَا مَخْمَصَةٌۭ فِى سَبِيلِ ٱللَّهِ وَلَا يَطَـُٔونَ مَوْطِئًۭا يَغِيظُ ٱلْكُفَّارَ وَلَا يَنَالُونَ مِنْ عَدُوٍّۢ نَّيْلًا إِلَّا كُتِبَ لَهُم بِهِۦ عَمَلٌۭ صَٰلِحٌ ۚ إِنَّ ٱللَّهَ لَا يُضِيعُ أَجْرَ ٱلْمُحْسِنِينَ ﴾

“It does not behove the people of the [Prophet's] City and the bedouin [who live] around them to hold back from following God's Apostle, or to care for their own selves more than for him -for, whenever they suffer from thirst or weariness or hunger in God's cause, and whenever they take any step which confounds those who deny the truth, and whenever there comes to them from the enemy whatever may be destined for them -[whenever anything thereof comes to pass,,] a good deed is recorded in their favour. Verily, God does not fail to requite the doers of good!”

Our life is social in nature. That is why everyone, according to his tastes and aptitudes, forms a circle of his own in which to spend his days and nights. It is necessary for those who fear God and want to tread the path of faith to befriend those who are sincere, truthful, and God-fearing, and who are consistent in their words and deeds. By keeping company with such people, one is transformed into a truthful person too. On the contrary, if one seeks the company of insincere, hypocritical persons, one will necessarily come under their influence. There are times when Islam has to be served by risking one’s life; there are times when Islam has to be served at the cost of suffering the pangs of hunger and thirst; there are times when one is exhausted struggling for the cause of God; there are times when one has to serve God and His prophet by sacrificing one’s peace of mind. On such occasions one feels like opting for the safer course and hesitates to go ahead and answer the call of one’s faith. One is oblivious of the fact that those were the very opportunities to give practical proof of one’s attachment to God, when by doing so, one could have expected to be found worthy of paradise.
