O Rasulallah! Is all that we say recorded for us? (and will we be punished for it)
May your mother be bereaved of you (understand well) that there is nothing more that throws people over their noses into Hell-Fire than the harvest of their tongues. Indeed you remain safe as long as you are silent but when you speak it will either be recorded in your favour (a good deed) or against you (a sin).
Note: "May your mother be bereaved of you" is, according to the Arab tradition, an address of affection and not of cursing.
