The times of prayer are originally three: at Fajr, from Zuhr until just before Maghrib, and from Maghrib until the end of the night.

The questioner : A question here says: I heard that the times of prayer are originally three: at Fajr, from Zuhr until just before Maghrib, and from Maghrib until the end of the night. However, the Messenger (peace and blessings be upon him) specified that it is better to pray Zuhr, 'Asr, Maghrib, and 'Isha in their known times, and that it is permissible to pray in only three times a day, as the Shi'ah do. What is your opinion? May Allah reward you with good.

The Shaykh : Repeat that for me.

The questioner : By Allah, it seems the question is incomplete!

The Shaykh : Allah the Exalted said: This is the verse that ... it contains three times: the declining of the sun, meaning its setting and tilting from the middle of the sky; to the darkness of the night, meaning the onset of night for the Maghrib prayer; and the recitation of Fajr, meaning the Fajr prayer. These are three times. The first time, which is defined by the declining of the sun, includes the Zuhr and 'Asr prayers. Therefore, it is permissible to combine them during travel, certainly, based on many hadiths, and in the case of staying put due to dire necessity. The darkness of the night includes the Maghrib and 'Isha prayers. Therefore, it is also established that they can be combined during travel without restriction, and in the case of staying put to remove hardship. And the recitation of Fajr, meaning the Fajr prayer. These are three times.
But as that suggests,The questioner : it is established from the Prophet (peace and blessings be upon him and his family) by the mass-transmitted Sunnah that Jibril (peace be upon him) came down to him and taught him the times of prayer over two days. On the first day, he prayed Fajr for him in the faint light of dawn. On the second day, he prayed Fajr for him when the sky had brightened and the sun was about to rise. He prayed Zuhr on the first day when the sun tilted from the middle of the sky, and on the next day he prayed Zuhr when the shadow of a thing became equal to it and the time of 'Asr was about to enter. He prayed 'Asr on the first day after the time of Zuhr had passed, and on the next day he prayed 'Asr before the sun turned yellow. He prayed Maghrib on the first day after the sun had set, and on the second day he prayed Maghrib just before the red twilight disappeared. He prayed 'Isha on the first day after the time of Maghrib had entered, and on the other day he prayed 'Isha at the middle of the night. And he said to him: Therefore, the Messenger (may Allah's prayers and peace be upon him) continued to lead the Muslims in his mosque in five prayers in five times. However, he once led the people in Medina in combining the Zuhr and 'Asr prayers, without fear, travel, or rain. He combined Zuhr and 'Asr, and combined 'Isha with Maghrib. Ibn 'Abbas narrated this to his followers, the Tabi'un. They said to him: O Abu al-'Abbas, what did he intend by that? He intended not to burden his Ummah. That is, when the Messenger (peace be upon him) combined with them in Medina, and there was no rain, no travel, and no fear among the excuses that permit combining, it was said to him: Why did the Messenger (peace be upon him) do that? He said: He intended not to burden his Ummah. It is permissible for a Muslim, in order to remove hardship, to combine the two prayers in the case of staying put, but on the condition that his habit is to separate the prayers and perform each of the five prayers in its known time in the Sunnah. This is how we should do it: we separate where the Messenger (peace be upon him) separated, so we pray each prayer in its time, and we combine where the Messenger (peace be upon him) combined, as a permission or to remove hardship.
Other than that?
