Rasulullah (Sallallaahu Alayhi Wasallam) replied to a similar question by
some of his Sahaaba (Radhiallaahu Anhum), ‘Do you doubt (in your religion)
just as the Christians and Jews doubted in their religion (during the time
of their Prophets).’
He further mentioned, ‘Even if Musa (Alayhis salaam) was alive today, he
would have followed me.’ If Musa (Alayhis salaam) would not seek guidance
from the Tawraat (old testament) and Eesa (Alayhis salaam) will follow the
Qur’aan upon his arrival on earth, how then can one we follow the scriptures
of Musa and Eesa (Alayhis salaam). They themselves regard the Qur’aan and
Ahaadith as their superguide despite being the direct recipients of
revelation of the Tawraat and Injeel. It is not permissible for Muslims to
seek any guidance from non-Muslim sources. The Qur’aan and Ahaadith is their
only and best source of guidance.
