Dhikr of Allah is the most excellent act of Allah’s servants and is stressed over a hundred times in the Holy Qur’an. It is the most praiseworthy work to earn Allah’s pleasure, the most effective weapon to overcome the enemy, and the most deserving of deeds in reward. It is the flag of Islam, the polish of hearts, the essence of the science of faith, the immunization against hypocrisy, the head of worship, and the key of all success.There are no restrictions on the modality, frequency, or timing of dhikr whatsoever. The restrictions on modality pertain to certain specific obligatory acts which are not the issue here, such as Salat. The Shari`a is clear and everyone knows what they have to do. Indeed, the Prophet said that the People of Paradise will only regret one thing: not having made enough dhikr in the world! Are not those who are making up reasons to discourage others from making dhikr afraid of Allah in this tremendous matter?
