Almost 30 years ago my friend's mum Hajjah Jawahir a Quran teacher read out the Quran to Haji Mohd Noor who is blind and he typed out one of the first braille versions of the Quran. Today he visited her and recited the Quran using the braille Quran for her to hear. She is now blind in one eye but still reads and teaches Quran.
