The ruling on sending blessings upon the Prophet after the dhikr during the sa'y

Question : Yes, Nasser. It is reported from 'Umar (may Allah be pleased with him) that he would send blessings upon the Prophet (peace and blessings be upon him) after the takbir and glorification, before the supplication.

Answer : There is no harm if it is authentic, for 'Umar has a sunnah (recommended practice) to be followed. But is it said to be from the category of what is prescribed, or from the category of what is permissible, as Ibn 'Umar added to the talbiyah: "Labbaik and sa'dayk, and the good is in Your hands, and the desire is toward You and the work"? The apparent precaution is to say so.
