The Prophet’s order to perform Hajj UT-TAMATTU
9. So when he wishes to make iHraam and is making Hajj-ul-Qirran, having brought the sacrificial animal with him, he should say: labbaikallaahumma bi-hajjah wa umrah
He also said: “O family of Muhammad – whoever from you makes Hajj, then let him say talbiyyah of an ‘Umrah in Hajj(12)” and this is At-Tamattu’ of `Umrah with Hajj.
10. And if he wishes when making talbiyyah he may state a condition to Allah fearing that which may prevent him (from completion of the Hajj) whether illness or fear – saying as the Prophet taught: allaahumma mahillee haithu habastanee
11. There is no special prayer for iHraam, however if it is time for prayer before iHraam, then he should pray and then put on iHraam following the example of the Rasoolullah who put on iHraam after prying zuhr. Imanway.com
