Some of the common mistakes that people commit when entering the Haram. They may be
explained as follows:
1. Entering through any specific gate.
Many people believe that it is essential for the pilgrim performing hajj or Umrah to enter through a specific gate of Masjid-al-haram. They believe that if they are performing Umarah, it is mandatory to enter through the gate called Baab al-Umrah and that it is prescribed in Shareeah. Others think that the right gate from which a person must enter is Baab as-salam. They are also of the notion that entering through any other gate is a sin or Makhroo. However, it must be noted that there is no basis for this in Shareeah. The pilgrim doing Hajj or ‘Umrah may enter through any gate, but when he enters the mosque he should enter with his right foot first and say what is narrated for entering all mosques, and send blessings upon the Prophet (peace and blessings of Allaah be upon him), and say, “Allaahumma aghfir li dhunoobi waftah li abwaab rahmatika (O Allaah forgive me and open to me the doors of Your Mercy).” Narrated by Muslim, 713. 2. Some people have invented some specific dua's for when one enters the mosque and sees the Kaaba.
They have introduced duas that are not part of noble sunnah of Prophet Muhammad(peace be upon him) and were not narrated from prophet Muhammad(peace be upon him). This is a kind of bid’ah (innovation). Worshipping Allaah with words, actions or beliefs that were not known to the Prophet (peace and blessings of Allaah be upon him) and his companions is innovation and misguidance which the Messenger of Allaah (peace and blessings of Allaah be upon him) warned us against. 3. Some people - even those who are not doing Hajj – mistakenly believe that the greeting for al-Masjid al-Haraam is tawaaf, in the sense that it is Sunnah for everyone who enters al-Masjid al-Haraam to do tawaaf, basing that on the view of some of the fuqaha’ that the Sunnah when entering al-Masjid al-Haraam is to do tawaaf.
Infact this is not true.masjid al-Haram is like any other mosque and the same manners apply to this mosque as applies to every other mosque. the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “When any one of you enters the mosque, let him not sit down until he has prayed two rak’ahs.” Narrated by al-Bukhaari, 444; Muslim, 714.
But if you enter al-Masjid al-Haraam to do tawaaf other than the tawaaf of Hajj or ‘Umrah, or for a voluntary tawaaf, then it is permissible for you to do tawaaf without praying two rak’ahs first. This is what is meant by saying that the greeting for al-Masjid al-Haraam is tawaaf. Based on this, if you enter with no intention to do tawaaf, rather you are waiting for the prayer or you are coming to attend a lesson etc, then al-Masjid al-Haraam is like any other mosque and it is Sunnah to pray two rak’ahs before you sit down, because the Prophet (peace and blessings of Allaah be upon him) enjoined that.
And Allah knows best.
