The Ishraq prayer

It is narrated from Sayyiduna Abdullah bin al-Harith (may Allah be pleased with him) that Sayyiduna Ibn Abbas (may Allah be pleased with them both) did not pray the Duha (forenoon) prayer until we took him to Sayyidah Umm Hani' (may Allah be pleased with her). I said to her: Tell Ibn Abbas (may Allah be pleased with them both) what you told us. Sayyidah Umm Hani' (may Allah be pleased with her) said: The Messenger of Allah (peace and blessings be upon him) came into my house, and he (peace and blessings be upon him) prayed eight rak'ahs of the Duha prayer. Sayyiduna Ibn Abbas (may Allah be pleased with them both) came out saying: I had read everything between the two covers of the Qur'an, yet only now have I come to recognise the Ishraq prayer, (whereas the Qur'an says): "They glorify (Allah) in the evening and at sunrise (Ishraq)" [Surah Sad: 18]. Then Ibn Abbas (may Allah be pleased with them both) said: This is the Ishraq prayer.
Abdullah bin Abbas (may Allah be pleased with them both) has also narrated another hadith from Umm Hani'.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that Sayyidah Umm Hani' bint Abi Talib (may Allah be pleased with her) told him that she said: O Messenger of Allah! My full brother Ali (may Allah be pleased with him) claims that he will kill the man to whom I have granted protection. The Messenger of Allah (peace and blessings be upon him) said: "Whomever you have granted protection, we too have granted protection."
