Asslamoaliekum! Be grateful to Allah(SWT) always as He himself says in Surah Ibrahim verse 7(14:7): * "And [remember] when your Lord proclaimed, 'If you are grateful, I will surely increase you [in favor]; but if you deny, indeed, My punishment is severe'".* Do we have any other option? No! Then be grateful to Allah(SWT). We should avoid complaining in the posts and in general in our lives.
