Zikr is the act of praising Allah with special words.
When we do zikr, we keep our intention in remembrance of Allah.
Some important zikr are:-
لَا إِلٰهَ إِلَّا اللهُ مُحَمَّدٌ رَسُوْلُ الله
سُبْحَانَ الله
الْحَمْدُ لله
اللهُ أَكْبَر
أَسْتَغْفِرُ الله
Conclusion:
Allah loves those Muslims who remember him most. The remembrance of Allah is done by praying namaz and doing zikr.
