Designating a Certain Day to Perform Qiyam Al-Layl
We are a group of people who gather to recite ma'thurat (selected supplications). Sometimes we agree on a certain day to offer Qiyam Al-Layl (Night Vigil Prayer) in congregation, but some other brothers blamed us for doing so under the pretext that gathering ourselves for the sake of dhikr (remembrance of Allah) is an innovation. Besides, they said assembling to offer Night Vigil Prayers, except in Ramadan, is an innovation, something the Prophet (peace and blessings be upon him) never did. What do you think about that? Is choosing the first Saturday in each month, for example, as a day for assembling considered to be an innovation ?
