What is meant by the rising of the sun in his saying (peace and blessings be upon him): “Whoever prays Fajr in congregation, then sits and remembers Allah until the sun rises… the hadith”?

Question:
May Allah reward you with good, and may He do you good. He says: I read in a hadith narrated by al-Tirmidhi and al-Tabarani: a Hajj and a 'Umrah, complete, complete, complete, or he returns with the reward of a Hajj and a 'Umrah. My question is: does this mean the rising of the sun when we see the light of the sun, or when we see the white thread from the black? May Allah reward you with good.

Answer:
By the rising of the sun, the actual rising of the sun is meant. One does not pray the two rak'ahs until the sun has risen the height of a spear. One does not pray at its rising; because the Prophet (peace and blessings be upon him) forbade prayer at the rising of the sun when it appears bright, because this is a time in which the polytheists worship and prostrate to it, and we are forbidden from imitating them. Also, because this is one of the means of shirk (associating partners with Allah). Voluntary prayer at the rising of the sun is not permissible. But when it has risen the height of a spear, he prays the two rak'ahs and then leaves, and he will have the reward mentioned by the Prophet (peace and blessings be upon him). May Allah send prayers upon him. This hadith [applies] if his intention is sound and Allah accepts it from him. Yes.
