His speech, laughter and rears:

He, sallallaahu ‘alayhi wa sallam, did not speak very much. He used to speak slowly and clearly, not too fast for hisspeech to be memorized, and not too slow that there would be periods of silence. His guidance was the most perfect of guidance.

Often, he, sallallaahu ‘alayhi wa sallam, repeated his words three times so people would understand it and when he greeted others he would do so three times3. He, sallallaahu ‘alayhi wa sallam, would be silent for long periods of time, speaking of nothing unnecessarily.

He, sallallaahu ‘alayhi wa sallam, used to say a lot in a few words.

He, sallallaahu ‘alayhi wa sallam, did not speak on matters that did not pertain to him. He, sallallaahu ‘alayhi wa sallam, only spoke of things that generated reward and whenever he disliked something his  facial expression would show it.

Most of his laughter was in the form of smiling. The most that would appear from his smile were his front molars. He, sallallaahu ‘alayhi wa sal-lam, would laugh at things that were funny or things that were considered amazing.

As for his crying:

 It was similar to his laughter. He, sallallaahu ‘alayhi wa sallam, did not breathe hard while crying. His eyes would tear up and
there would be some sounds in his chest.

Sometimes he, sallallaahu ‘alayhi wa sallam, would cry because someone had died, sometimes out of fear for his nation, sometimes out of fear from Allah, and sometimes when listening to the Quran. He, sallallaahu ‘alayhi wa sallam, cried out of love as well as out of glorification to Allah.

When his son Ibraaheem died, the Prophet of Allah, sallallaahu ‘alayhi wa sallam, cried out of mercy. And he, sallallaahu ‘alayhi wa sallam, cried when seeing one of his daughters on her deathbed.

And he, sallallaahu ‘alayhi wa sallam, cried while listening to ‘Abdullaah ibn Mas’ood (a companion) reciting Chapter An-Nisaa’ of the Quran. He, sallallaahu ‘alayhi wa sallam, also cried when ‘Uthmaan ibn Math’oon (a companion) passed away, and while praying the “eclipse prayer.

He, sallallaahu ‘alayhi wa sallam, cried while sitting near the grave of one of his daughters and he used to cry while praying the night prayer
