The verse of Isra’ in the Qur’an is clear not liable to hesitation or reluctance in saying that Allah had caused His servant to travel by night from Al-Masjid Al-Haram to Al-Masjid Al-Aqsa like you say ; I traveled by night from such and such place to such and such place. So, there is no room for hesitation and asking whether this was with body or spirit, or awake or during sleep. Also, it is inappropriate to disagree regarding the meaning of this night journey or regarding the word ‘Abd, i.e., servant, and whether it refers to the spirit, to the body or to both, as it has happened between those claiming bodily Isra and others claiming spiritual Isra.
During the Mi’raj, the Prophet(P) is reported to have received from God the command of five daily prayers (salah) that all Muslims must perform. Upon his return to Mecca, the Prophet instituted these prayers. It is significant to note that he made Jerusalem the direction (al-Qiblah) which Muslims must face while doing their prayers (narrated by al-Bukhari, 41 and by Muslim, 525). Jerusalem is thus called Ula al-Qiblatain (the first qiblah). The Prophet (P) and the early community of Islam worshipped towards the direction of Jerusalem during their stay in Mecca. After the Hijra’ (migration), Muslims in Medina also continued to pray facing Jerusalem for almost seventeen months until God commanded the Muslims to change their direction of prayer from Jerusalem to Mecca (Qur’an 2:142 – 150). These established facts clearly signifies the importance of Jerusalem in Islam.
