Surah R’ad, verse 4:
‘And in the earth are neighbouring tracts, and gardens of vines, and green crops (fields), and date-palms, growing into two or three from a single stem root, or otherwise (one stem root for every palm ), watered with the same water, yet some of them We make more excellent than others to eat. Verily, in these things, there are Ayât (proofs, evidences, lessons, signs) for the people who understand.’
Ref to bold part:
Some people look the same in their appearance but when you deal with them, they are completely different people. Don’t be judgemental – people are individuals and individuals are different. Your 5 fingers are different, 5 kids are diffrent, 5 friends, etc. Likewise, the ‘taste’ of people are different – some people are sour, sweet, bitter, salty, etc :).
Always look at ourselves – don’t judge people. How are you? How do you affect others? How do people view you? Ex Yusuf (as) – how did people view him? Muhsin, saadiq, sideeq – because of his character and actions. So ask: How do I affect people?
