Be honest anytime and everywhere! Because deceiving people is not the moral of follower of the Prophet ﷺ. The Prophet ﷺ always teaches us to be honest in every matters.
A hadith from Abu Hurayrah said:
أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم مَرَّ عَلَى صُبْرَةِ طَعَامٍ فَأَدْخَلَ يَدَهُ فِيهَا فَنَالَتْ أَصَابِعُهُ بَلَلاً فَقَالَ ” مَا هَذَا يَا صَاحِبَ الطَّعَامِ ” . قَالَ أَصَابَتْهُ السَّمَاءُ يَا رَسُولَ اللَّهِ . قَالَ ” أَفَلاَ جَعَلْتَهُ فَوْقَ الطَّعَامِ كَىْ يَرَاهُ النَّاسُ مَنْ غَشَّ فَلَيْسَ مِنِّي ”
The Messenger of Allah ﷺ happened to pass by a heap of eatables (corn). He thrust his hand in that (heap) and his fingers were moistened. Then he said to the owner of that heap of eatables (corn):
What is this? The corn seller replied: O Messenger of Allah, these have been drenched by rainfall. The Holy Prophet remarked: Why did you not place this (the drenched part of the heap) over other eatables so that the people could see it? Who deceives people is not part of me (is not my follower [Saheeh Muslim].
The true Muslim never try deceiving people. They always say the truth and action honestly.
