[22].Surah Al-Hajj [The Pilgrimage]: Ayat 49-50

Ayat 49. Say (O Muhammad  [SAWW](PBUH): "O mankind! I am (sent) to you only as a plain warner."

Ayat 50. So those who believe (in the Oneness of Allah Islamic Monotheism) and do righteous good deeds, for them is forgiveness and Rizqûn Karim (generous provision, i.e. Paradise). Ayat 51. But those who strive against Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), to frustrate and obstruct them, they will be dwellers of the Hell-fire.[Tafseer] Say: "O men! I am (sent) to you only to give a clear warning. It is the Messenger's duty to convey the warning in the clearest terms to the  wicked. It is not part of his duty to coerce them or judge them, or bring on the Punishment for them. That only rests with Allah. But the warning itself is full of Mercy: for it gives the highest hope to the repentant sinner who turns and comes to Allah. "Those who believe and work righteousness, for them is forgiveness and a sustenance most generous. The "sustenance" must be construed in the widest sense, spiritual as well as intellectual and physical. The reward of righteousness is far more generous than any merit there may be in the creature following the Will of his Creator. "But those who strive against Our Signs, to frustrate them,- they will be Companions of the Fire." It will not be in their power to frustrate Allah's Plan; all they will do is to go further and further down in their spiritual state, deeper and deeper into their Hell

Hazrat Saad bin Abu Waqqas (May Allah be pleased with him) reported: Messenger of Allah [SAWW](PBUH) said, "Allah loves a slave who is pious, free of all wants (as (generous provision is provided by Allah) and the unnoticed.''

[Muslim Chapter 42, Hadith # 7072]. 

Lesson : as mentioned above in Surah Al-Hajj Ayat 50."those who believe (in the Oneness of Allah Islamic Monotheism) and do righteous good deeds, for them is forgiveness and Rizqûn Karim (generous provision, i.e. Paradise)." Partial isolation, according to this Hadith, is recommendable for the obedience and worship of Allah. It is particularly approved when the prevalent corruption and social intercourse endanger religion, or its implementation looks no more feasible.
