Musannaf Ibn Abi Shaybah

Hazrat Ka'b says: Hazrat Musa (peace be upon him) submitted (in the Divine Court): O my Lord! (Please tell me,) are You (so) near to me that (whenever I wish to present something in Your presence) I should speak to You in a whisper, or are You (so) far from me that (at the time of presenting my needs) I should speak to You in a raised voice? Allah, the Most Glorious and Exalted, said: O Musa! I am near to every one who remembers Me. Hazrat Musa (peace be upon him) then submitted: O my Lord! Sometimes we are in such a state that we do not consider it befitting to mention You. Allah, the Blessed and Exalted, said: What is that state (in which you do not consider it befitting to mention Me)? He (Musa) replied: In a state of impurity and at the time of relieving oneself. Allah, Glorious is His Majesty, said: O Musa, remember Me in every state (however, at the time of relieving oneself and other such occasions where it is not appropriate to mention Me with the tongue, then remember Me in your heart).
