Imaam Hasan (may Allah be pleased with him) says, I asked my (maternal) uncle Hind ibn Abi Haalah, who always described the noble features of Messenger of Allah ﷺ to describe to me the manner in which Messenger of Allah ﷺ spoke. He replied that Messenger of Allah ﷺ was always worried (about the hereafter). And always busy thinking (about the attributes of Allah and the betterment of the Ummah). Because of these things he was never free from thought and never rested (or because of worldly affairs he did not gain rest, but gained rest and contentment from religious well being. It is mentioned in the hadith that the coolness of my eyes is in salaah). He always spoke clearly from beginning to end. (He did not speak in a manner where only half sentences are spoken and the other half remained in the mind of the speaker, as is prevalent among snobbish high-minded and proud people). He spoke concisely, where the words are less and meaning more. (Mulla Ali Qaari has collected forty such ahaadith in his commentary which are very short. Those who wish may refer to it and memorise it). Every word was clearer than the previous one. There was no nonsensical talk, nor was there half-talks where the meaning was not complete and could not be grasped. He was not short-tempered, nor did he disgrace anyone. He always greatly appreciated the blessings of Allah even though it might be very minute, he did not criticize it.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 Messenger of Allah ﷺ was mostly a smile, at that moment his mubarak front teeth glittered like white shining hailstone
حَدَّثَنَا سُفْيَانُ بْنُ وَكِيعٍ، قَالَ: حَدَّثَنَا جُمَيْعُ بْنُ عُمَرَ بْنِ عَبْدِ الرَّحْمَنِ الْعِجْلِيُّ، قَالَ: حدَّثنِي رَجُلٌ مِنْ بَنِي تَمِيمٍ مِنْ وَلَدِ أَبِي هَالَةَ زَوْجِ خَدِيجَةَ يُكْنَى أَبَا عَبْدِ اللهِ، عَنِ ابْنٍ لأَبِي هَالَةَ، عَنِ الْحَسَنِ بْنِ عَلِيٍّ، قَالَ: سَأَلْتُ خَالِي هِنْدُ بْنُ أَبِي هَالَةَ، وَكَانَ وَصَّافًا، فَقُلْتُ: صِفْ لِي مَنْطِقَ رَسُولِ اللهِ صلى الله عليه وسلم، قَالَ: كَانَ رَسُولُ اللهِ صلى الله عليه وسلم مُتَوَاصِلَ الأَحْزَانِ، دَائِمَ الْفِكْرَةِ، لَيْسَتْ لَهُ رَاحَةٌ، طَوِيلُ السَّكْتِ، لا يَتَكَلَّمُ فِي غَيْرِ حَاجَةٍ، يَفْتَتِحُ الْكَلامَ، وَيَخْتِمُهُ بِاسْمِ اللهِ تَعَالَى، وَيَتَكَلَّمُ بِجَوَامِعِ الْكَلِمِ، كَلامُهُ فَصْلٌ، لا فُضُولَ، وَلا تَقْصِيرَ، لَيْسَ بِالْجَافِي، وَلا الْمُهِينِ، يُعَظِّمُ النِّعْمَةَ وَإِنْ دَقَّتْ لا يَذُمُّ مِنْهَا شَيْئًا، غَيْرَ أَنَّهُ لَمْ يَكُنْ يَذُمُّ ذَوَّاقًا وَلا يَمْدَحُهُ، وَلا تُغْضِبُهُ الدُّنْيَا، وَلا مَا كَانَ لَهَا، فَإِذَا تُعُدِّيَ الْحَقُّ، لَمْ يَقُمْ لِغَضَبِهِ شَيْءٌ، حَتَّى يَنْتَصِرَ لَهُ، وَلا يَغْضَبُ لِنَفْسِهِ، وَلا يَنْتَصِرُ لَهَا، إِذَا أَشَارَ بِكَفِّهِ كُلِّهَا، وَإِذَا تَعَجَّبَ قَلَبَهَا، وَإِذَا تَحَدَّثَ اتَّصَلَ بِهَا، وَضَرَبَ بِرَاحَتِهِ الْيُمْنَى بَطْنَ إِبْهَامِهِ الْيُسْرَى، وَإِذَا غَضِبَ أَعْرَضَ وَأَشَاحَ، وَإِذَا فَرِحَ غَضَّ طَرْفَهُ، جُلُّ ضَحِكِهِ التَّبَسُّمُ، يَفْتَرُّ عَنْ مِثْلِ حَبِّ الْغَمَامِ.
