Ruling on calling a child ‘Arfaan or Ayman
Question

                We are thinking of naming our child Arfaan.

I would like to know the meaning of this name and whether it is a good meaning name for our child.

While on this topic I would also like to know the meaning of the name Aiman, which I think means lucky, fortunate in arabic but I am not so sure.
Praise be to Allah.
	The father should choose a good name for his son, because a 
	person’s name is a title which says something about him.

	There is no need to choose a name of which the meaning is not 
	known. Among the good names which are known to people there are sufficient 
	names that the Muslim has no need to do that.

	It is well known in Arabic that ‘Irfaan [not ‘Arfaan] means 
	knowledge.

	It says in Lisaan al-‘Arab (9/236):

	‘Ifraan means knowledge. End quote.

	The ‘uruffaan or ‘iriffaan is a huge grasshopper, like a 
	locust, with a crest.

	‘Iriffaan was used as a man’s name.

	See: al-Mukhassas (2/353); al-Qaamoos al-Muheet 
	(p. 836).

	The word ‘urfaan is the dual form of the word ‘urf, which 
	refers to the comb of a rooster. A deek afraq is a rooster that has two 
	combs.

	Al-Mukhassas 
	(1/84).

	One of the narrators of hadith was called Mu‘allaa ibn 
	‘Urfaan; he is da‘eef (weak).

	See: at-Taareekh al-Kabeer by al-Bukhaari (7/395); 
	al-Ikmaal by Ibn Maakoolaa (6/200).

	‘Irfaan was a well-known female singer. She was the mother of 
	the singer Ibraaheem ibn Abi’l-‘Abees ibn Hamdoon.

	Al-Ikmaal 
	(6/200).

	Thus it becomes clear that these names were narrated from the 
	Arabs.

	‘Iriffaan and ‘Urfaan are men’s names.

	‘Irfaan is a woman’s name.

	With regard to ‘Arfaan, we do not know of it in the Arabic 
	language, so it is not appropriate to use this as a name.

	But if it has a good meaning that is well known among you, 
	according to your language and customs, then there is nothing wrong with 
	using this name, even though it is better not to. Whatever the case, there 
	is no shar‘i virtue in giving such names.

	With regard to Ayman, it is a good name, which comes from the 
	word yumn, meaning barakah (blessing).

	It says in Taaj al-‘Aroos (36/302):

	Yumn means barakah (blessing). If a man is blessed with good 
	fortune, he may be described as maymoon or ayman (meaning fortunate). End 
	quote.

	Ayman is also the opposite of aysar (meaning unfortunate).

	It says in Lisaan al-‘Arab (13/459):

	Ayman and maymanah are the opposite of aysar and maysarah. 
	End quote.

	Among the Sahaabah was Ayman ibn Umm Ayman.

	So there is nothing wrong with this name, and it comes under 
	the heading of optimism and the hope that this child will be blessed.

	And Allah knows best.
