Q 4:76

And what is wrong with you that you fight not in the cause of Allah, and for those weak, ill-treated and oppressed among men, women, and children, whose cry is: "Our Lord! Rescue us from this town whose people are oppressors; and raise for us from You one who will protect, and raise for us from You one who will help. (75)Those who believe, fight in the cause of Allah, and those who disbelieve, fight in the cause of the Taghut. So fight against the friends of Shaytan; ever feeble indeed is the plot of Shaytan (76) Encouraging Jihad to Defend the Oppressed Allah encouraged His believing servants to perform Jihad in His cause and to strive hard to save the oppressed Muslims in Makkah, men, women and children who were restless because of having to remain there. This is why Allah said, الَّذِينَ يَقُولُونَ رَبَّنَا أَخْرِجْنَا مِنْ هَٰذِهِ الْقَرْيَةِ (whose cry is: "Our Lord! Rescue us from this town), referring to Makkah. In a similar Ayah, Allah said, وَكَأَيِّن مِّن قَرْيَةٍ هِيَ أَشَدُّ قُوَّةً مِّن قَرْيَتِكَ الَّتِي أَخْرَجَتْكَ (And many a town, stronger than your town which has driven you out)[47:13] Allah then describes this town, الظَّالِمِ أَهْلُهَا وَاجْعَل لَّنَا مِن لَّدُنكَ وَلِيًّا وَاجْعَل لَّنَا مِن لَّدُنكَ نَصِيرًا (whose people are oppressors; and raise for us from You one who will protect, and raise for us from You one who will help) meaning, send protectors and helpers for us. Al-Bukhari recorded that Ibn 'Abbas said, "I and my mother were from the oppressed (in Makkah)." Allah then said, الَّذِينَ آمَنُوا يُقَاتِلُونَ فِي سَبِيلِ اللَّهِ وَالَّذِينَ كَفَرُوا يُقَاتِلُونَ فِي سَبِيلِ الطَّاغُوتِ (Those who believe, fight in the cause of Allah, and those who disbelieve, fight in the cause of the Taghut.) Therefore, the believers fight in obedience to Allah and to gain His pleasure, while the disbelievers fight in obedience to Shaytan. Allah then encourages the believers to fight His enemies, فَقَاتِلُوا أَوْلِيَاءَ الشَّيْطَانِ إِنَّ كَيْدَ الشَّيْطَانِ كَانَ ضَعِيفًا (So fight against the friends of Shaytan; ever feeble indeed is the plot of Shaytan).
