He did not criticize food, nor over-praised it (The reason for not criticizing food is clear, that it is a blessing from Allah. The reason for not praising it is because it might be felt that one is gluttonous. Nevertheless, he praised food if it was to make someone happy, and sometimes praised some special things). He was never angered for anything materialistic. (The reason being that he did not pay much attention, and did not care much about materialistic things).
If someone exceeded the limits in religious matters or against the truth, he became so angry that no one could endure it, nor could anybody stop it till he avenged it. If for some reason he made a gesture or pointed at something, he did it with a full hand. (The ulama say the reason being that it is against humbleness to point with one finger only. Some ulama say it was his noble habit to signal oneness of Allah with one finger, therefore he did not signal anyone in that manner). When he was surprised by something he turned his hands, and when he spoke sometimes while talking, he moved his hands, he sometimes hit the palm of his right hand with the inside part of his left thumb. When he became angry with someone, he turned his face away from that person, and did not pay attention to that person or he forgave that person. When he was happy due to humility it seemed as if he had closed his eyes. The laugh of Rasoolullah sallallahu alaihe wasallam was mostly a smile, at that moment his mubarak front teeth glittered like white shining hailstone
