Riyad Us-Saliheen (Gardens of the Righteous)

Chapter 293
Prohibition of following the Manners of Satan and Disbelievers

1634. Jabir (May Allah be pleased with him) said: I heard the Messenger of Allah (PBUH) as saying: "Do not eat with your left hand, because Satan eats and drinks with his left hand.''
[Muslim].

1635. Ibn `Umar (May Allah be pleased with them) said: The Messenger of Allah (PBUH) said, "No person should eat and drink with his left hand for Satan eats with his left hand and drinks with his left hand.''
[Muslim].

Commentary:  It is a pity that in imitation of Europeans, many Muslims now eat and drink with their left hand and thus please Satan.

1636. Abu Hurairah (May Allah be pleased with him) said: I heard the Messenger of Allah (PBUH) as saying: "Jews and Christians do not dye their hair, so act differently from them.''
[Al-Bukhari and Muslim].

Commentary:  We learn from this Hadith that the Prophet (PBUH) has advised the Muslims to dye the hair of their head and beard with yellow or red colour. They have been forbidden from dying the hair with black colour, as will be explained in the coming Ahadith.

Some religious scholars have regarded this as something desirable. Therefore, it is not necessary to dye the hair of head and beard. But this is certainly better. Since any resemblance with the Jews and Christians is unlawful, not dying the hair will create a resemblance with them. Therefore, in such a situation the colouring will be necessary, otherwise it will be Mustahabb, that is to say desirable.
