At the Miqat, after wearing ihram garments and praying two rak'ahs, declare your intention: For Umre say 'Labbayk Allahumma Umratan' and for Hac say 'Labbayk Allahumma Hajjan.' Then begin the Telbiye. If you fear being unable to complete, add: 'Allahumma mahilli haythu habastani.'
لَبَّيْكَ اللَّهُمَّ عُمْرَةً / لَبَّيْكَ اللَّهُمَّ حَجًّا. اللَّهُمَّ مَحِلِّي حَيْثُ حَبَسْتَنِي
Labbayk Allahumma 'Umratan / Labbayk Allahumma Hajjan. Allahumma mahilli haythu habastani.
Meaning: Here I am O Allah, answering Your call for Umre / Here I am O Allah, answering Your call for Hac. O Allah, my place of ending (ihram) is wherever You prevent me (if unable to complete).
Source: Sahih al-Bukhari #5089Entering ihram at the Miqat is the gateway to the entire hac ibadeti. Hz. Peygamber (sallallahu aleyhi ve sellem) showed that the intention must be declared verbally. Jabir's hadith of the Farewell Hac in Sahih Muslim (1218) details Hz. Peygamber's complete ritual at the Miqat. The conditional clause provides ease for those with valid concerns about completing the hac ibadeti.
لَبَّيْكَ اللَّهُمَّ عُمْرَةً / لَبَّيْكَ اللَّهُمَّ حَجًّا. اللَّهُمَّ مَحِلِّي حَيْثُ حَبَسْتَنِي
The Prophet (peace be upon him) said: 'The conditional clause is for anyone who fears being prevented from completing the pilgrimage. Duba'ah bint al-Zubayr came to him and said: O Messenger of Allah, I want to perform Hajj but I am ill. He said: Perform Hajj and stipulate the condition: O Allah, my place of ending is wherever You prevent me.'
