A hadith about the one who recites Surat al-Ikhlas a thousand times

Question:
This questioner asks, Shaykh Salih, and says: What is the authenticity of this hadith: “Whoever recites Surat al-Ikhlas, *Qul huwa Allahu Ahad*, a thousand times in one night, has purchased himself from Allah”? What does that mean? How does a Muslim or a person purchase himself from Allah?

Answer:
I do not know this hadith. However, Surat al-Ikhlas, as the Prophet (peace and blessings be upon him) said, is equal to one-third of the Qur'an, so it has great virtue. But specifying a certain number of recitations of Surat al-Ikhlas requires evidence, and I do not know any evidence for that. Yes, it is reported that it is recited along with Surat al-Falaq and Surat al-Nas, with each surah repeated three times in the morning and evening adhkar. This is a dhikr for which there is evidence. As for a thousand times or more, I do not know anything about that. Yes.
