Is there a prayer and sermon for seeking rain: Abu Hanifah said the rain prayer is not prayed in congregation and has no sermon

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Jibril led me in prayer at the House of Allah twice. He led me in the Isha prayer when the twilight had disappeared, and the next day he led me in the Isha prayer at the first third of the night, and he said: 'This time (of prayer) is the time (of prayer) of the prophets before you, and the time (of Isha) is between these two (fixed) times.'"

Abu Bakr bin Abi Musa narrates from his father that a questioner came to the Prophet (peace and blessings be upon him) and asked him about the times of the prayers. He gave him no answer. Then he ordered Sayyiduna Bilal (may Allah be pleased with him), and he called the iqamah for the Isha prayer at the disappearance of the twilight. Then the next day he offered the Isha prayer at a third of the night. Then he said: "Where is the one who asked about the times? The time (of Isha) is between these two (fixed) times."

Husayn bin Bashir narrates from his father, who said: Muhammad bin Ali and I entered upon Sayyiduna Jabir bin Abdullah (may Allah be pleased with him). We asked him: "Tell us how the prayer was performed with the Prophet (peace and blessings be upon him)." He said: "The Prophet (peace and blessings be upon him) led us in the Isha prayer when the twilight had disappeared. Then the next day the Prophet (peace and blessings be upon him) led us in the Isha prayer when a third of the night had passed."

Safiyyah bint Abi Ubayd states that Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) wrote the prayer times in a letter to the commanders of the armies. He said: "Pray the Isha prayer when the twilight has disappeared. If you have some occupation, then you have until a third of the night (as its time), and do not busy yourselves away from the prayer. Whoever sleeps after that, may Allah not grant his eyes sleep." Sayyiduna Umar (may Allah be pleased with him) said this three times.

It is reported from Ibrahim; he said that the time of Isha lasts until a quarter of the night. It is mentioned that the view of (Imam) Abu Hanifah is: The time of Isha lasts until half of the night.
