The Difference Between the Fajr Prayer and the Subh Prayer

Many people confuse the Fajr prayer and the Subh prayer, as if they are two separate categories. Is there any guidance on this? May Allah reward you with good.
Answer: The Subh prayer is the Fajr prayer, so there is no difference. The Subh prayer is the Fajr prayer; there are not two prayers. The Fajr prayer is the Subh prayer, and it is two obligatory rak'ahs by the consensus of the Muslims, performed after the appearance of the dawn and before the sunrise. It is best to perform it in the darkness before full daylight. The man performs it in congregation, except for the sick person who cannot, in which case he prays it in his house. The woman also prays it in her house before the sunrise. It is not permissible to delay it until after the sunrise; rather, it must be performed before the sunrise, and it is best to perform it at the beginning of the time, in the darkness when the dawn is clear and has split. It is called the Fajr prayer and it is called the Subh prayer. It is obligatory for the Muslim to take care of it and preserve it in its time. It is not permissible to delay it until the sunrise, as some people do, delaying it until they get up for work. This is a great abomination, and it is disbelief according to a group of the scholars of knowledge. We ask Allah for safety from it.
So it is obligatory to be cautious and to preserve it in its time, both the man and the woman.
It is prescribed to perform two rak'ahs of the regular voluntary prayer (sunnah rawatib) before it, two rak'ahs of the regular voluntary prayer before it. The Prophet (peace and blessings be upon him) used to do this and preserve it. Aisha (may Allah be pleased with her) said: And he used to say (peace and blessings be upon him): .
So one should preserve it. The Fajr sunnah is two light rak'ahs, in which one recites al-Fatihah and "Say: O you disbelievers" in the first, and al-Fatihah and "Say: He is Allah, the One" in the second. This is the best. Or one recites the verse from al-Baqarah: [al-Baqarah:136] the verse, in the first, and in the second the verse from Al-Imran: [Al-Imran:64] to its end. The Prophet (peace and blessings be upon him) did both of these. If one recites something else, there is no harm. If one recites something else with al-Fatihah, there is no blame. But that one recites what the Prophet (peace and blessings be upon him) recited is better. And one recites these two surahs also in the sunnah of Maghrib after al-Fatihah: "Say: O you disbelievers" in the first and "Say: He is Allah, the One" in the second. And one recites them also in the two rak'ahs of tawaf. All of this was done by the Prophet (peace and blessings be upon him). He recites these two surahs after al-Fatihah in the sunnah of Fajr, the sunnah of Maghrib, and the sunnah of tawaf. And if one recites in some instances in the sunnah of Fajr a second verse from al-Baqarah: [al-Baqarah:136] and a verse from Al-Imran in the second, which is His saying, the Exalted: [Al-Imran:64] the verse, then this is also a sunnah, done by the Prophet (peace and blessings be upon him). And if one recites in these rak'ahs something else, there is no blame; for His saying, the Exalted: [Al-Muzzammil:20]. Yes.
