Fulfillment of Oaths

۞ إِنَّ ٱللَّهَ ٱشْتَرَىٰ مِنَ ٱلْمُؤْمِنِينَ أَنفُسَهُمْ وَأَمْوَٰلَهُم بِأَنَّ لَهُمُ ٱلْجَنَّةَ ۚ يُقَـٰتِلُونَ فِى سَبِيلِ ٱللَّهِ فَيَقْتُلُونَ وَيُقْتَلُونَ ۖ وَعْدًا عَلَيْهِ حَقًّا فِى ٱلتَّوْرَىٰةِ وَٱلْإِنجِيلِ وَٱلْقُرْءَانِ ۚ وَمَنْ أَوْفَىٰ بِعَهْدِهِۦ مِنَ ٱللَّهِ ۚ فَٱسْتَبْشِرُوا۟ بِبَيْعِكُمُ ٱلَّذِى بَايَعْتُم بِهِۦ ۚ وَذَٰلِكَ هُوَ ٱلْفَوْزُ ٱلْعَظِيمُ

Indeed, Allāh has purchased from the believers their lives and their properties [in exchange] for that they will have Paradise. They fight in the cause of Allāh, so they kill and are killed. [It is] a true promise [binding] upon Him in the Torah and the Gospel and the Qur’ān. And who is truer to his covenant than Allāh? So rejoice in your transaction which you have contracted. And it is that which is the great attainment.

وَخُذْ بِيَدِكَ ضِغْثًا فَٱضْرِب بِّهِۦ وَلَا تَحْنَثْ ۗ إِنَّا وَجَدْنَـٰهُ صَابِرًا ۚ نِّعْمَ ٱلْعَبْدُ ۖ إِنَّهُۥٓ أَوَّابٌ

[We said], "And take in your hand a bunch [of grass] and strike with it and do not break your oath." Indeed, We found him patient, an excellent servant. Indeed, he was one repeatedly turning back [to Allāh].
