He (rahimahullaah) said:

”Do not accept an invitation, except the invitation of one whom your hearts feel good/are at ease about his food.”

He (rahimahullaah) said:

 ”Wealth used to be  hated in the past, but today it is the armour of the believer.”

He (rahimahullaah) said:

”The lawful does not carry extravagance.”
