What is the ruling on reciting (Surat al-Ikhlas) a thousand times, and likewise (Surat al-Falaq) a thousand times?

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the ruling on reciting Surat al-Ikhlas a thousand times, and likewise Surat al-Falaq a thousand times or a hundred times, and making it a daily routine?

Answer:
O brothers, the dhikr (remembrance of Allah) is restricted to what has been transmitted regarding its number, its formulas, and its times. It is restricted to what has been transmitted. We do not answer with a number from our own minds for which there is no evidence. We do not answer with dhikr at a specific time without evidence. It must be from evidence from the Shari'ah, because dhikr is worship, and acts of worship are based on specific texts.
There were people in the time of Ibn Mas'ud (may Allah be pleased with him) who gathered in the mosque of Kufa. They had pebbles with them, and one of them would say, "Subhan Allah a hundred times," and they would count a hundred with the pebbles. "Allahu Akbar a hundred times," and they would count a hundred. "Alhamdulillah a hundred times," and they would count a hundred. He stood over them and said, "What is this you are doing?" They said, "O Abu 'Abd al-Rahman, we are remembering Allah." He said, "You are better than the Messenger (peace and blessings be upon him). Either you are more guided than the Messenger of Allah (peace and blessings be upon him), or you have opened a door to misguidance." He (may Allah be pleased with him) condemned this action because it is not from the Sunnah of the Messenger (peace and blessings be upon him).
That is, specifying a number for dhikr requires evidence. Specifying a time for dhikr requires evidence. We do not answer with something from our own minds. Acts of worship are based on specific texts in their formulas, their times, and their words. Yes. A thousand times, and he says, "Read this twenty times." What is the evidence? It must be from evidence.
