Zikr

The Holy Prophet SAW said, "Those who are admitted into Paradise will not regret over anything of this world, except the time spent without zikr in their life"

Note: After their entry into paradise, when they will see the huge reward (as large as mountains) for remembering Allah once, they will feel extremely sorry over their loss caused by the time spent without zikr, as can be well imagined.

In this world, there are such blessed persons who would not relish this life it is were spent without the zikr of Allah.

Hafiz Ibn Hajar rah writes in his book "Munabbihaat" that Yahya bin Mu'aaz Raazi rah used to Say in his supplication: O Allah! the night is no good unless spent in communion with you, the day is no good unless spent in worshipping You, this life is no good without Your zikr, the next life will be on good without forgiveness from You, and Paradise will not be enjoyable without beholding You.

Hadhrat Sirri ra says, "I Saw Jurjani swallowing roasted barley flour. He told me that he had compared the time taken in chewing bread and in eating barley flour "SUBHANALLAH" seventy times in that time. Therefore, he had not taken bread for forty years, and had lived by swallowing barley flour alone."

It is said about Mansoor bin Mu'tamar that he never spoke to anybody after Ishaa prayers for forty years.

Similarly, it is said about Rabee' bin Hatheem that it was his practice for twenty years that he noted down what he talked during the day,and would check at night whether that talking was necessary or not. Those pious scholars were particular that every moment of their life was spent in zikr and in nothing else..
