We should rather say aameen instead of inshaAllah while making dua!!
“Do not be impatient over the acceptance of Duas. In other words, don’t say: I’ve made Dua repeatedly but to no avail.”
[Bukhari & Muslim]
Anas bin Malik رضي الله ﺗﻌﺎﻟﯽٰعنه narrated,
“The Messenger of Allah صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ said,
‘When one of you makes dua, he should be firm in his supplication and should not say,
“O ALLAH (سُبْحَانَهُ وَتَعَالَى), if You wish then grant me (my request),” for indeed, there is none who can compel Him.’“
This hadith is recorded by Imam Muslim in his Sahih, and he in fact has a whole chapter in his book dedicated to this topic. It indicates towards one of the etiquettes of making dua, which is to have a firm resolve when doing so and to have full trust in ALLAH (سُبْحَانَهُ وَتَعَالَى) that He will grant us our request. It teaches us that it is disliked to say things like “In-sha Allah” when making dua. Instead we should rather say “Aameen“.
Da’wah ALLAH (سُبْحَانَهُ وَتَعَالَى)
