speak good, because useless conversation only causes loss. On the basis of four reasons Hujjat-ul-Islam Imam Muhammad Ghazali رَحْمَةُ اللهِ تَعَالٰی عَلَيْه has mentioned the harm of useless conversations:

1- Kiraman Katibeen (those respected angels who record deeds) have to write down useless conversation, therefore, a person should feel shy from them and should not give them the trouble of writing down useless conversation.

2- Regarding condemnation of useless conversation, he رَحْمَةُ اللهِ تَعَالٰی عَلَيْه mentions the second reason. It is not good that the Book of deeds full of useless conversation be presented to the Merciful Allah عَزَّوَجَلَّ.

3- The third reason for the condemnation of useless conversation is that a person will be ordered in the court of Allah عَزَّوَجَلَّ in front of all the creation to read out his Book of deeds. Now, the terrifying severities of the Day of Judgement will be in front of him. Human will be without clothes; he will be incredibly thirsty; his back will be bent due to hunger; he will be stopped from going to Paradise, and every type of comfort will be stopped for him. (Just ponder! How worrying it would be to read out a Book of deeds full of useless conversation in such troublesome situation!)

4- The fourth reason for condemnation of useless conversation is that on the Day of Judgement a person will be rebuked for useless conversation and he will be made to feel embarrassed. That person will have no answer to this and he will feel deeply ashamed in the blessed Court of Allah عَزَّوَجَلَّ. (Minhaj-ul-‘Aabideen, pp. 67)
