Shaykh Yasir Qadhi moves on to discuss verses 22 to 24 which deal with topics such as prohibition against speaking without knowledge and avoidance of emotions when fighting for the truth. Also, we are acquainted with the etiquette of saying 'in sha Allah'.
In the verses, we see how Allah teaches us the usage of the phrase - in Sha Allah, when we are referring to an event of the future such that in the event of its non occurrence due to any reason, we will not have fallen into falsehood. Saying the holy phrase reaffirms our firm belief in Allah.
