۞ إِنَّ ٱللَّهَ ٱشْتَرَىٰ مِنَ ٱلْمُؤْمِنِينَ أَنفُسَهُمْ وَأَمْوَٰلَهُم بِأَنَّ لَهُمُ ٱلْجَنَّةَ ۚ يُقَٰتِلُونَ فِى سَبِيلِ ٱللَّهِ فَيَقْتُلُونَ وَيُقْتَلُونَ ۖ وَعْدًا عَلَيْهِ حَقًّۭا فِى ٱلتَّوْرَىٰةِ وَٱلْإِنجِيلِ وَٱلْقُرْءَانِ ۚ وَمَنْ أَوْفَىٰ بِعَهْدِهِۦ مِنَ ٱللَّهِ ۚ فَٱسْتَبْشِرُوا۟ بِبَيْعِكُمُ ٱلَّذِى بَايَعْتُم بِهِۦ ۚ وَذَٰلِكَ هُوَ ٱلْفَوْزُ ٱلْعَظِيمُ
Indeed, Allah has purchased from the believers their lives and their properties [in exchange] for that they will have Paradise. They fight in the cause of Allah, so they kill and are killed. [It is] a true promise [binding] upon Him in the Torah and the Gospel and the Qur'an. And who is truer to his covenant than Allah? So rejoice in your transaction which you have contracted. And it is that which is the great attainment.
Commentary
Sequence
Previous verses carried a condemnation of those staying behind without a valid excuse and missing the Jihad. The present verses take up the merit of mujahidin.
The background of revelation
As explained by the majority of commentators, these verses were revealed about the participants of Bai'atul-'Aqabah (the pledge of allegiance to the Holy Prophet ﷺ at al-'Aqabah) which was taken from the Ansar of Madinah before Hijrah in 'Makkah al-Mukarramah. Therefore, despite that the entire Surah is Madani, these verses have been termed as Makki.
'Al-'Aqabah' is part of a mountain. Here, it refers to the 'Aqabah that forms a part of the mountain along the Jamratu al-'Aqabah (the stone pillar of 'Aqabah) in Mina. (In our time, due to the increased number of Hujjaj [ Hajj pilgrims ], this part of the mountain has been leveled to form a smooth surface with the only exception of Jamarah [ the stone pillar ] which still stands there). It is on this 'Aqabah that a pledge of allegiance بیعۃ (bai'ah) was taken from the people of Madinah thrice. The first pledge came in the eleventh year of the Prophet's advent. Six persons embraced Islam, gave the pledge and returned to Madinah. When they arrived there, Islam and the Prophet of Islam became the talk of the town. Next year, it was during the Hajj season that twelve people assembled at the same place. Out of these, five had taken part in the first pledge while the other seven were new. All of them took the pledge. By that time, the number of Muslims in Madinah had increased to more than forty. They requested that someone should be sent to teach Qur'an to them. The Holy Prophet ﷺ sent Sayyidna Mus` ab ibn ` Umair ؓ . He taught Qur'an to Muslims present there as well as conveyed the message of Islam around, as a result of which major groups of people in Madinah entered the fold of Islam.
After that, in the thirteenth year of the Prophet's advent, seventy men and women assembled at the same place. This is the third Bai'atu al-'Aqabah - and the last. Generally, when reference is made to Bai'atu al-'Aqabah, it means this very Bai'ah (pledge of allegiance). This pledge made it binding on participants that they would uphold the basic beliefs (` aqa'id عقَایٔد ) and deeds (a` mal اَعمَال ) of Islam, and would particularly be ready to take part in Jihad against the disbelievers, and protect and support the Holy Prophet ﷺ when he migrates and reaches Madinah. In this connection, Sayyidna ` Abdullah ibn Rawahah ؓ submitted, ` ya rasulallah, a compact is being made at this time. If there are any conditions regarding your Lord or regarding yourself, let these be mentioned there clearly.' He said, ` As for Allah Ta` ala, I lay down the condition that all of you shall worship Him - and worship none but Him. As for myself, the condition is that you shall protect me as you protect your own lives, wealth, property and children.' They asked, ` if we fulfill these two conditions, what shall we get in return?' He said, ` you will get Jannah جَنَّت .' All in delight, they said, ` we are pleased with this deal, so pleased that we shall never request on our own that it be cancelled nor shall we like it to be …
