The family after their lost will need our support emotionally and financially, we encourage anyone want to be part of that support to donate as much as you can. Our prophet (PBUH) said that:
"Whoever fulfilled the needs of his brother, Allah will fulfill his needs; whoever brought his (Muslim) brother out of a discomfort, Allah will bring him out of the discomforts of the Day of Resurrection, and whoever screened a Muslim, Allah will screen him on the Day of Resurrection . "
رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ َ: قَال
" مَنْ كَانَ فِي حَاجَةِ أَخِيهِ كَانَ اللَّهُ فِي حَاجَتِهِ ، وَمَنْ فَرَّجَ عَنْ مُسْلِمٍ كُرْبَةً فَرَّجَ اللَّهُ عَنْهُ بِهَا كُرْبَةً مِنْ كُرَبِ يَوْمِ الْقِيَامَةِ ، وَمَنْ سَتَرَ مُسْلِمًا سَتَرَهُ اللَّهِ يَوْمَ الْقِيَامَةِ."
May Allah reward you all.
