Read Ruku 32 of the Quran

حَـٰفِظُوا۟ عَلَى ٱلصَّلَوَٰتِ وَٱلصَّلَوٰةِ ٱلْوُسْطَىٰ وَقُومُوا۟ لِلَّهِ قَـٰنِتِينَ ﴿٢٣٨﴾

Maintain with care the [obligatory] prayers and [in particular] the middle prayer and stand before Allah, devoutly obedient.

فَإِنْ خِفْتُمْ فَرِجَالًا أَوْ رُكْبَانًۭا ۖ فَإِذَآ أَمِنتُمْ فَٱذْكُرُوا۟ ٱللَّهَ كَمَا عَلَّمَكُم مَّا لَمْ تَكُونُوا۟ تَعْلَمُونَ ﴿٢٣٩﴾

And if you fear [an enemy, then pray] on foot or riding. But when you are secure, then remember Allah [in prayer], as He has taught you that which you did not [previously] know.

وَٱلَّذِينَ يُتَوَفَّوْنَ مِنكُمْ وَيَذَرُونَ أَزْوَٰجًۭا وَصِيَّةًۭ لِّأَزْوَٰجِهِم مَّتَـٰعًا إِلَى ٱلْحَوْلِ غَيْرَ إِخْرَاجٍۢ ۚ فَإِنْ خَرَجْنَ فَلَا جُنَاحَ عَلَيْكُمْ فِى مَا فَعَلْنَ فِىٓ أَنفُسِهِنَّ مِن مَّعْرُوفٍۢ ۗ وَٱللَّهُ عَزِيزٌ حَكِيمٌۭ ﴿٢٤٠﴾

And those who are taken in death among you and leave wives behind - for their wives is a bequest: maintenance for one year without turning [them] out. But if they leave [of their own accord], then there is no blame upon you for what they do with themselves in an acceptable way. And Allah is Exalted in Might and Wise.

وَلِلْمُطَلَّقَـٰتِ مَتَـٰعٌۢ بِٱلْمَعْرُوفِ ۖ حَقًّا عَلَى ٱلْمُتَّقِينَ ﴿٢٤١﴾

And for divorced women is a provision according to what is acceptable - a duty upon the righteous.

كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَكُمْ ءَايَـٰتِهِۦ لَعَلَّكُمْ تَعْقِلُونَ ﴿٢٤٢﴾

Thus does Allah make clear to you His verses that you might use reason.
