Hazrat Qatadah says that Hasan liked very much that even during travel, prayers should be performed at their prescribed times.

Hazrat Umar bin Musa says that I asked Hazrat Abu Ja'far, "Which prayer is the most virtuous?" He replied, "The one that is performed at its earliest time."

Hazrat Saad says that wasting time is a very big mistake.

Hazrat Umm Farwah asked the Holy Prophet (peace and blessings be upon him): "Which deed or which prayer is the best?" He replied, "To perform the prayer at its earliest time."

It is narrated from Hazrat Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: Hazrat Jibreel led me in prayer twice at the House of Allah. He led me in the Zuhr prayer when the sun had declined just the width of a sandal strap. Then he led me in the Asr prayer when the shadow of everything became equal to its length. Then he led me in the Maghrib prayer at the time when the fasting person breaks his fast. Then he led me in the Isha prayer when the twilight disappeared. Then he led me in the Fajr prayer at the time when eating and drinking becomes forbidden for the fasting person. Then, on the next day, he led me in the Zuhr prayer when the shadow of everything became equal to its length. Then he led me in the Asr prayer when the shadow of everything became twice its length. Then he led me in the Maghrib prayer at the time when the fasting person breaks his fast. Then he led me in the Isha prayer after one third of the night had passed. Then he led me in the Fajr prayer when it had become bright. Then he turned to me and said, "O Muhammad! This was the time of prayer for the Prophets before you; the time for your prayer is also between these two times."

Hazrat Abu Musa narrates that a man asked the Holy Prophet (peace and blessings be upon him) about the timings of prayers. The Prophet did not give him any answer but ordered Bilal, so he gave the iqamah at the time when dawn had appeared. The Prophet led the prayer at that time. Then Bilal gave the iqamah at the time when the announcer said that the sun had just declined or was about to decline, although that announcer knew the timings best. Then for the Asr prayer, the iqamah was given when the sun was still high. Then for the Maghrib prayer, the iqamah was given when the sun had set. Then for the Isha prayer, the iqamah was given when the twilight had disappeared. Then on the next day, the Prophet led the Fajr prayer at the time when the announcer said that the sun had risen or had not risen, and that announcer knew the timings best. Then the Prophet led the Zuhr prayer close to the time of the previous day's Asr prayer. And he led the Asr prayer at the time when the announcer said that the sun had turned red. Then he led the Maghrib prayer before the twilight had disappeared, and the Isha prayer after the first third of the night had passed. Then he said, "Where is the one who asked about the timings of the prayers? The time between these two times is the time for the prayer."

It is narrated from Hazrat Abu Hurairah that the Messenger of Allah, peace and blessings be upon him, said: Every prayer has a beginning time and an ending time. The beginning time of Zuhr is when the sun declines (from its zenith). The ending time of Zuhr is when the time of Asr begins. The beginning time of Asr is when its time begins, and its ending time is when the sun becomes yellow. The beginning time of Maghrib is when the sun sets, and its ending time is when the twilight disappears. The beginning time of Isha is when the twilight disappears, and its ending time is when half the night passes. The beginning time of Fajr is when the dawn appears, and its ending time is when the sun rises.

Hazrat Abu Barzah says that the Noble Prophet (peace and blessings be upon him) used to perform the Zuhr prayer when the sun would decline from the middle of the sky towards the west. He would perform the Asr prayer at such a time that after offering the prayer, any one of us could circle around the outskirts of Madinah on his mount and return, and the sun would still be shining. The narrator says that he forgot the time that was mentioned for Maghrib, and the Prophet (peace and blessings be upon him) considered it preferable to delay the Isha prayer a little. He (peace and blessings be upon him) would finish the Fajr prayer at such a time when there was enough light that a person could recognize the one sitting next to him. The Prophet (peace and blessings be upon him) used to recite between sixty and a hundred verses in Fajr.

Hazrat Jabir bin Abdullah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) used to offer the Zuhr prayer at midday after the sun had passed its zenith, the Asr prayer when the sun was still bright, and the Maghrib prayer after the sun had set. He would sometimes offer the Isha prayer late and sometimes early. When he saw that people had gathered, he would offer it early, and if people delayed in coming, he would offer it late. And he used to offer the Fajr prayer in darkness.

It is narrated from Hazrat Anas that the Noble Prophet (peace and blessings be upon him) was asked about the time of the Fajr prayer. So he instructed Hazrat Bilal to give the call to prayer (adhan) when the dawn appeared, and then on the next day to give the adhan when it became light. Then he said, "Where is the one who asked the question? The time for Fajr is between these two times."
