Hazrat Mujahid, Hazrat Tawus, and Hazrat Ata say that if a person puts on the Ihram for Hajj, if he wishes, he may combine Umrah with it and become a Qarin, and send a Hadi (sacrificial animal) as well.

15662 - From Ata and Tawus, or one of them, regarding a man who enters into ihram for Hajj: they said, if he wishes, he may combine it with Umrah and thus be a Qarin, and he should offer a sacrificial animal.

It is narrated from Hazrat Ibn Umar (may Allah be pleased with them both) that when the Noble Prophet (peace and blessings be upon him) arrived in Makkah Mukarramah, he (peace and blessings be upon him) performed istilam (touching or kissing) of the Hajar Aswad and the Rukn Yamani, and did not perform istilam of any other corner.

Hazrat Ata says that among my teachers I found Hazrat Ibn Abbas (may Allah be pleased with them), Hazrat Jabir, Hazrat Abu Hurairah (may Allah be pleased with him), and Hazrat Ubaid bin Umair, that they would perform istilam (touching/kissing) of the Hajar Aswad and the (Yemeni) corner, and would not perform istilam of any other corner.

Hazrat Ibrahim bin Abdul A'la reports that I saw Hazrat Suwaid bin Ghaflah; he performed istilam (touching/kissing) of all the corners of the Ka'bah.

It is narrated from Hazrat Ata that when Hazrat Umar performed Hajj, he performed Istilam of the Black Stone (Hajar Aswad), and Hazrat Ya'la bin Umayyah (may Allah be pleased with him) performed Istilam of all the corners. Hazrat Umar said to him: O Ya'la (may Allah be pleased with him)! What have you done? Hazrat Ya'la (may Allah be pleased with him) replied that he had performed Istilam of all the corners because there is nothing of the Ka'bah that should be left (without Istilam). Hazrat Umar said: Did you not see that the Noble Prophet (peace and blessings be upon him) performed Istilam of only the Black Stone? Hazrat Ya'la (may Allah be pleased with him) replied: Why not. Hazrat Umar said: Then is there not a model for you in this? Hazrat Ya'la (may Allah be pleased with him) replied: Why not.

Hazrat Mujahid would very rarely omit the touching (Istilam) of Hajar Aswad and Rukn Yamani during the odd circuits of Tawaf.

Hazrat Mujahid says that the two corners adjacent to the Hajar Aswad should not be touched (for Istilam).

Hazrat Abdullah saw Hazrat Muawiyah performing Tawaf of the Ka'bah and touching all the corners, and he said that there is nothing among them that should be left out.

Hazrat Abbad saw Hazrat Ibn Zubair doing this and he said that there is nothing in it that should be left out.
