Jihad (striving in Allah's cause)

إِنَّ ٱلَّذِينَ ءَامَنُوا۟ وَٱلَّذِينَ هَاجَرُوا۟ وَجَـٰهَدُوا۟ فِى سَبِيلِ ٱللَّهِ أُو۟لَـٰٓئِكَ يَرْجُونَ رَحْمَتَ ٱللَّهِ ۚ وَٱللَّهُ غَفُورٌ رَّحِيمٌ

Indeed, those who have believed and those who have emigrated and fought in the cause of Allāh - those expect the mercy of Allāh. And Allāh is Forgiving and Merciful.

ٱنفِرُوا۟ خِفَافًا وَثِقَالًا وَجَـٰهِدُوا۟ بِأَمْوَٰلِكُمْ وَأَنفُسِكُمْ فِى سَبِيلِ ٱللَّهِ ۚ ذَٰلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ

Go forth, whether light or heavy, and strive with your wealth and your lives in the cause of Allāh. That is better for you, if you only knew.
