Answer: Saiyidul Mursaleen, Imaamul Mursaleen, Khwatamun Nabeiyeen, ‘Hu’dur Pak Swallallahu ‘Alaihi wa Sallam himself discussed his esteemed Bilaadat Shareef.

A famous and reliable Book of Hadith Shareef widely studied in all Madrasah of our country is “Meshkatul Masabeeh” which contains a chapter titled ‘Fajaile Saiyidul Mursaleen'(page-513) states as follows:

عنحضرتعرباضبنساريةرضىاللهتعالىعنهأنرسولاللهصلىاللهعليهوسلمقالانىعبداللهوخاتمالنبيينوانآدملمنجدلفىطينتهوسأخبركمعنذلكدعوةأبىابراهيمعليهالسلاموبشارةحضرتعيسىعليهالسلامورؤياامىالتىرأت،وكذلكامهاتالنبيينيرين،وأنامرسولاللهصلىاللهعليهوسلمرأتحينوضعتهنوراأضاءتلهقصورالشام

Translation: Hazrat Irbaaj Ibne Saariyah Rwadialla Ta’ala Anhu relates, Noor-e-Mujassam ‘Habeebullah ‘Hu’dur Pak Swallallahu ‘Alaihi wa Sallam said: Certainly I am ‘Abd’ or ‘Habeeb’ and ‘Khwatamun Nabeiyeen’ of Allah Rwabbul Aalameensince when Hazrat Adam Alaihis Salam was still ‘mingled with clay’ (yet to born). It is revealed to you that I am the ‘prayer’ of Hazrat Ibrahim Khalilullah Alaihis Salam, the ‘Good News’ of Isaa Ruhullah Alaihis Salam, the ‘Dream’ of my mother (Hazrat Amina Alaihas Salam). The dream which my mother dreamt like the mothers of all other Rwasul/Nabeiyeen (Alaihimus Salam) had also dreamt. During Bilaadat Shareef of ‘Hu’dur Pak Swallallahu ‘Alaihi wa Sallam his esteemed Mother observed a ‘Noor’ (Light ) that enlightened the Palace of Syria. Subhaanallah !

Saiyidul Mursaleen, Imaamul Mursaleen, Khwatamun Nabeiyeen, ‘Hu’dur Pak Swallallahu ‘Alaihi wa Sallam himself discussed his esteemed Bilaadat Shareef, now if we do the same why should it be termed as Bidaat?
