Quran 2:239 — The Heifer (Al-Baqarah)

Under unusual circumstances, you may pray while walking or riding. Once you are safe, you shall commemorate GOD as He taught you what you never knew.

[2:238] You shall consistently observe the Contact Prayers, especially the middle prayer, and devote yourselves totally to GOD.

[2:240] Those who die and leave wives, a will shall provide their wives with support for a year, provided they stay within the same household. If they leave, you commit no sin by letting them do whatever they wish, so long as righteousness is maintained. GOD is Almighty, Most Wise.
