Allah (Subhanahu Wa Ta’ala) says in the Quran: ”In order that you may not grieve at the things that you fail to get, nor rejoice over that which has been given to you.

Allah madaukaki yana cewa: “Domin kada ku yanke kauna da bakin ciki kan abin da ya kubuce muku, kuma kada ku yi farin ciki da abin da ya zo muku”[4].
