The Opening Invocation in Obligatory and Voluntary Prayers
Machine translationRead the Arabic original
The questioner:
Honorable Shaykh, is the inquiry only regarding the obligatory prayer, or not?
The Shaykh:
It is for both the obligatory and the voluntary prayers. The opening invocation in prayer is done in the obligatory and in the voluntary. The Prophet (peace and blessings be upon him) used to do it when he stood up for the late-night prayer.
The questioner:
And the guest of the Shaykh, and Abu, seeking help, and Abeer.
The Shaykh:
Seeking refuge with Allah in the first rak'ah suffices along with the opening invocation. Yes.
