The supplication prescribed when passing the Black Stone and when at al-Safa and al-Marwah

Question:
Honorable Shaykh, this questioner says: What is the prescribed supplication in 'Umrah, especially for the one who passes by the Black Stone, and likewise at al-Safa and al-Marwah? What is the prescribed supplication?

Answer:
The prescribed supplication is that he points to the Black Stone if he is far from it, pointing to it and saying takbir, saying Allahu Akbar. As for the supplication itself, it is during the sa'y (walking between al-Safa and al-Marwah). He begins the supplication from the time he starts the sa'y until it ends; the whole time is a place for supplication and dhikr (remembrance of Allah). Yes.
