Tradition n. 342

قالَ رَسُولُ الله صلی الله عليه و آله و سلم:

ثَلاثَةٌ يُحِبُّهَا اللّهُ: قِلَّةُ الكَلامِ وَ قِلَّةُ المَنامِ وَ قِلَّةُ الطَّعامِ، ثَلاثَةٌ يُب غِضُهَا اللّهُ: كَث رَةُ الكَلامِ وَ كَث رَةُ المَنامِ وَ كَث رَةُ الطَّعامِ.

The Holy Prophet (S) said: “There are three traits which Allah loves (in people): briefness in speech, short (length) of sleep, and small (portion) of food; while there are three traits which He dislikes (in them): loquaciousness, oversleeping, and overeating.”

Tradition n. 343

قالَ رَسُولُ الله صلی الله عليه و آله و سلم:

تَنَظَّفُوا بِكُلِّ مَا اس تَطَع تُم ، فَاِنَّ اللّهَ تَعالى بَنَـى الاِسـلامَ عَلَـى النَّظافَةِ، وَلَن يَد خُلَ الجَنَّةَ اِلاّ كُلُّ نَظِيفٍ.

The Holy Prophet (S) said: “Try to be clean as much as you are able to. Verily, Allah has based the foundation of Islam on cleanliness; hence, never can a person enter Paradise but the clean ones.”

Tradition n. 345

عَنِ الحَسَنِ ب نِ جَه مٍ قالَ: قالَ اَبُوالحَسَنِ مُوسَى بنُ جَعفَرٍ عليه السلام :

خَم سٌ مِنَ السُّنَنِ فِي الرَّأ سِ وَ خَم سٌ فِي الجَسَدِ: فَاَمَّا الّتي في الرّأ سِ: فَالسِّـواكُ، وَ اَخ ذُ الشّارِبِ، وَ فَر قُ الشَّع رِ، وَ المَضمَضَة وَ الاِس تِن شاقُ، وَ اَمَّا الَّتي فِي الجَسَدِ، فَالخِتانُ، وَ حَل قُ العانَةِ، وَ نَتفُ الاِب طَي نِ، وَ تَقلِيمُ الأظ فارِ، وَ الاِستِن جاءُ.

Imam Musa Ibn Ja'far, the seventh Imam, (‘a) said:

“There are five sunnah about the head and five others related to the body. The first five concerning the head, are: washing the mouth, trimming the moustache, combing the hair, and drawing up water through the mouth and nostrils.

The second five, concerning the body, are: circumcision, shaving the pubic hair, depilating the armpits, clipping the nails, and cleansing the privy parts (with water, tissue, cloth, etc., while water is preferable).”

Tradition n. 346

قالَ الإمامُ اَميرُالمُؤمِنينَ عَلِيٌّ عليه السلام لِلحَسَنِ عليه السلام :

أَلا اُعَلِّمُكَ أَربَعَ خِصالٍ تَستَغنِي بِها عَنِ الطِّبِّ؟ قالَ: بَلى، قالَ: لاَ تَج لِس عَلَى الطَّعامِ إِلاّ وَأَن تَ جائِعٌ وَلاَ تَقُم عَنِ الطَّعامِ إِلاّ وَ أَن تَ تَش تَهِيهِ وَ جَوِّدِ المَض ـغَ وَ إذا نِم تَ فَاع رَض نَف سَـكَ عَلَى الخَلاءِ فَاِذَا اس تَع مَل تَ هَذا اِس تَغ نَي تَ عَنِ الطِّبِّ

Imam Amir al-Mu’minin ‘Ali (‘a) told Imam Hasan (‘a): “Shall I teach you four traits by which you will be in no need of any medical treatment?”

“Yes,” Imam Hasan answered. Then, ‘Ali (‘a) said:

Do not sit for food (in order to eat) unless you are hungry;

And, do not leave the (table of) food but you still have an appetite for it;

Chew (your food in your mouth) well;

And, when you want to go to bed, (primarily) go to the water-closet to ease nature.

If you take these in action, you will be in no need of any medical treatment.”
