There is no blame upon the blind nor the lame nor the ill nor yourselves when you eat from your houses or the houses of your fathers or the houses of your mothers or the houses of your brothers or the houses of your sisters or the houses of your father's brothers or the houses of your father's sisters or the houses of your mother's brothers or the houses of your mother's sisters or houses of which the keys you possess or houses of your friend; there is no blame upon you whether you eat together or separately, but when you enter houses, give greetings of peace upon yourselves, a greeting from Lord Allah, blessed and wholesome, thus does Allah make clear to you His verses so that you may think utilizing your intelligence.
It is told in verse 38: 24: “Many of the mingling men and women are doing unjust to one another except those who are believers and are doing righteous deeds, and they are a few”. The Three-Time-Knower Lord is explaining dos and don’ts through Adhikr to maintain a peaceful life in society. But the Arabic Quran reading Fujjar who read these verses by hiding and rejecting Adhikr are at the forefront of every heinous and shameful deed all over the world. They have become the worst in that they are seeing the sexual organs of opposite genders in their so-called prayer as explained in verse 4: 43. They have an evil concept about the Lord Allah so that the Lord’s wrath and curse happen upon them, and Hell is kept prepared for them as told in verse 48: 6. They are denoted as the worst creatures among 1000 communities of the Lord’s creatures as explained in verse 8: 22. So the read, heard and touched verses will argue and witness against them and will push them into Hell as explained in verse 3: 199. So the believer who testifies Adhikr will try not to mingle with such worst Fujjar under any circumstances.
Peace is one of the Best Names of Lord Allah as mentioned in verse 53: 23. The greeting that one should greet the other should be: “May Peace be upon you”. But if any among the Fujjar or Kuffar happens to greet the believer, he should only return to the way how they greeted him, since the believer is commanded to do Jihad with Adhikr against these hypocrites and Kuffar as explained in verse 9: 73. And believer will never greet hypocrites first. But he will consider all mankind alike and will not show any discrimination based on religion, caste, sex, color, etc. See explanation 4: 86; 9: 71-72, 84-85, and 23: 29-31.
