Hazrat Ibn Sirin states that the Companions believed that if a woman performed Hajj while she was pregnant, then Hajj would also be considered as performed on behalf of the child in her womb.

Hazrat Mujahid says that if a Bedouin performs Hajj, then that Hajj will suffice for Islam on his behalf.

It is narrated from Hazrat Ibn Abbas (may Allah be pleased with them both) that at the place of Rauha, some riders met the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) asked, "Who are you?" They replied, "Muslims." Then they asked, "And who are you?" The Prophet (peace and blessings be upon him) said, "The Messenger of Allah (peace and blessings be upon him)!" A woman raised her child and asked, "Is there Hajj for this one as well?" The Prophet (peace and blessings be upon him) replied, "Yes, and the reward is for you."

Hazrat Tawoos says that a child's Hajj will be sufficient for him until he reaches adulthood.

Ibrahim says that the ihram of a child will be made in the same way as that of an adult, and he will be kept away from perfume, and he will be circumambulated (taken for tawaf), and he will be present at the rituals, and the talbiyah will be recited on his behalf.

It is narrated in a similar manner from Hazrat Ata as well, but with the addition that the child should not be made to lead the prayer, and if they wish, they may put a shirt on him, and if they wish, they may not.

Hazrat Abu Bakr Siddiq performed Tawaf with Hazrat Abdullah bin Zubair in one garment.

Hazrat Ibn Umar (may Allah be pleased with both of them) and Hazrat Aisha (may Allah be pleased with her) both used to separate children during Hajj and would perform Sa'i between Safa and Marwah with them.

Hazrat Ata says that a child should be made to avoid in ihram the same things that an adult avoids, that is, adornment and fragrant things.

Hazrat Jabir narrates that we performed Hajj with the Noble Prophet (peace and blessings be upon him) and we would recite the Talbiyah on behalf of the children.
