عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((لَا يَمْنَعُكُمْ أَذَانُ بِلَالٍ مِنَ السَّحُورِ، فَإِنَّ فِي بَصَرِهِ شَيْئًا))
Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Do not let Bilal’s (may Allah be pleased with him) adhan prevent you from taking suhoor, because his eyesight is somewhat impaired.
