I would much appreciate your reply with regards: the permissibility of reading the SAYYIDUL ISTIGHFAAR during our sujood followed be some verses from the Holy Qur'an.
Praise be to Allah.Reciting Quraan in sujood is not allowed because of the hadeeth
narrated by Ibn Abbaas (may Allaah be pleased with him) in which the Prophet
(peace and blessings of Allaah be upon him) said: Indeed I have been told not to
recite Quraan in rukoo and sujood. (Reported by Muslim, 738). But if some words from the Quraan are recited as duaa, such as
(interpretation of the meaning): Our Lord! Give us in this world that which is
good and in the Hereafter that which is good, and save us from the torment of the
Fire! [al-Baqarah 2:201], then there is nothing wrong with this. As for reciting
Sayyid al-istighfaar (the best form of seeking forgiveness) in sujood, there is nothing
wrong with this, because this is counted as duaa. And Allaah knows best.
