Make a will for family before death arrives 2:180-182
2:180 Written for any of you when death arrives, if he leaves behind goods, is the will for his parents and relatives with kindness. This is a duty incumbent on the cautious.
2:182 He who fears injustice or sin on the part of a testator and brings about a settlement among the parties incurs no guilt. Allah is the Forgiver and the Most Merciful.
