English Translation of Al-Quran
[30].Surah Ar-Rum [The Romans]
Ayat 53. And you (O Muhammad [SAWW](PBUH) cannot guide the blind from their straying; you can make to hear only those who believe in Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), and have submitted to Allah in Islam (as Muslims).
Tafseer of Surah Al Rum (The Romans) Ayat 53. Nor canst thou lead back the blind from their straying: only those wilt thou make to hear, who believe in Allah’s signs and submit (their wills in Islam). Then there is the case of men about whom the saying holds true, that none are so blind as those who will not see. They prefer to stray in the paths of wrong and of sensei pleasures. How can they be guided in any way? The only persons who gain by spiritual teaching are those who bring a mind to it—who believe and submit their wills to Allah’s Will. This is the central doctrine of Islam (Cf. 43:40)
English Translation of Hadith
Hazrat Anas (May Allah be pleased with him) said: The Messenger of Allah [SAWW](PBUH) said, “During the Miraj (the Night of Ascension), I saw a group of people who were scratching their chests and faces with their copper nails. I asked, `Who are these people, O Jibril?’ Jibril replied: `These are the people who ate flesh of others (by backbiting) and trampled people’s honor.”
[Abu Dawud Hadith # 4878]
Lesson : These are the people who ate the flesh of others” is a metaphor for backbiting. “To trample people’s honor” is akin to harming their goodwill and honor. The punishment for these things mentioned in Hadith makes their seriousness obvious.
