Hawzah News Agency – The merciful prophet of Islam, peace be upon him and his household says:

ليسَ إيمانُ مَن رآني بعَجَبٍ ولكنّ العَجبَ كلَّ العَجبِ لِقومٍ رأَوا أوْراقاً فيها سَوادٌ فآمَنوا بهِ أوّلِهِ وآخِرهِ.

'The faith of one who has seen me is no great wonder, but what is truly amazing is for the people who have only seen pages with black [ink] on it [i.e. the Qur'an] and have believed in it from beginning to end.'
