Can a Muslim suspect others or spy on others or do backbite?

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ ٱجۡتَنِبُواْ كَثِيرٗا مِّنَ ٱلظَّنِّ إِنَّ بَعۡضَ ٱلظَّنِّ إِثۡمٞۖ وَلَا تَجَسَّسُواْ وَلَا يَغۡتَب بَّعۡضُكُم بَعۡضًاۚ أَيُحِبُّ أَحَدُكُمۡ أَن يَأۡكُلَ لَحۡمَ أَخِيهِ مَيۡتٗا فَكَرِهۡتُمُوهُۚ وَٱتَّقُواْ ٱللَّهَۚ إِنَّ ٱللَّهَ تَوَّابٞ رَّحِيمٞ ١٢

Believers, avoid being excessively suspicious, for some suspicion is a sin. Do not spy, nor backbite one another. Would any of you like to eat the flesh of his dead brother? You would surely detest it. Have fear of Allah. Surely Allah is much prone to accept repentance, is Most Compassionate.

Aey logon jo imaan laaye ho, bahut gumaan (suspicion)karne se parheiz karo ke baaz gumaan (suspicion) gunaah hote hain. Tajassus (jasusi) na karo aur tum mein se koi kisi ki geebat na karey. kya tumhare andar koi aisa hai jo apne marey(dead) huey bhai ka gosht khana pasand karega? Dekho, tum khud is se gheen khate ho. Allah se daro, Allah bada tawbah qabool karne wala aur Raheem hai
