The actual meaning of zikr is for a person to fulfil the command of Allah Ta‘ala that relates to him in every given situation. Allah Ta‘ala commands us in the Qur’aan Majeed saying:
یٰۤاَیُّهَا الَّذِیْنَ اٰمَنُوْا لَا تُلْهِکُمْ اَمْوَالُکُمْ وَلَاۤ اَوْلَادُکُمْ عَنْ ذِکْرِ اللّٰه
O you who believe! Do not let your wealth or children turn you away from the remembrance (command) of Allah Ta‘ala. (Surah Munaafiqoon v. 9)
Hence, while one is at home interacting with his family and children, or while one is engaged in trade and commerce, if he ensures that he remains obedient to Allah Ta‘ala and does not break His commands while fulfilling these worldly needs, then even though he is engaged in these occupations, he will be regarded as a person engaged in the remembrance of Allah Ta‘ala.
