Surat Yūsuf - سورة يوسف

الر ۚ تِلْكَ آيَاتُ الْكِتَابِ الْمُبِينِ

Muhsin Khan: Alif-Lam-Ra. [These letters are one of the miracles of the Quran, and none but Allah (Alone) knows their meanings]. These are the Verses of the Clear Book (the Quran that makes clear the legal and illegal things, legal laws, a guidance and a blessing).
