Dear miracle114,
Salaam,
I find your question to be so general in the manner presented. However, to generally quickly suggest 5 of them among many others, I can say (1) maintaining one’s own household well and guarding its welfare to one’s utmost (proper housing, catering, education, morals, etc) (2) spending wealth in charity to the needy (3) construction of buildings meant for orphanages, worship (mosques) etc (4) funding community welfare schemes (e.g, paying water & electricity bills) (5) travelling around the world to designated places of religiously historical significance…etc.
Hopefully that helps.
Regards,
Athmani.
