Meaning of Irfan
Irfan is an indirect Qur’anic name for boys. Irfan means “wisdom”, or more correctly, Wisdom with a capital W. It refers to all that is good and true of thoughts and deeds. It is derived from the Ain-R-F root (to know, to recognize), which is used in many places in the Holy Qur’an,  as in the following verse:
Wa Jā’a ‘Ikhwatu Yūsufa Fadakhalū `Alayhi Fa`arafahum Wa Hum Lahu Munkirūna — Sura Yusuf, Chapter 12, Verse 58
And the brethren of Joseph came, and entered unto him, and he knew them, but they knew him not — Holy Qur’an, 12:15, translation by A.J. Arberry.
The Term Irfan in Islamic Mysticism
The term ‘irfan (gnosis), which literally meaning knowledge, is widely applied in Islamic mysticism. In the mystical context, like another term in the same family, mari’fa, which is also translated as gnosis, the knowledge is of certain kind which can be achieved neither through the senses nor experience, nor through reason nor narration, but rather is acquired by inner witnessings and interior unveilings.  It is that knowledge that unites man with God after penetrating and transforming him completely.
The famous prayer of the Prophet Muhammad (s.a.s) sums up the end toward which the gnostic strives with all his mind, soul and body:
“O God, deliver us from preoccupations with worldly vanities and show us the nature of things ‘as they really are’. Remove from our eyes the veil of ignorance, and show us things as they really are…Deliver us from ourselves, and accord us intimate knowledge of Thee.” 
Meaning of Sinan
Sinan is an Arabic name for boys meaning spearhead. It is derived from the root word S-N-N which is used in the Qur’an. Sinan is pronounced [(SI)mple] + [(NA)p + (N)ew] with emphasis on the second syllable. Wikipedia mentions that the name might also be related to the Ancient Greek name Sinon.
In Ismaili history, the name Sinan is associated with the revered personality of Rashid al-din Sinan, one of the greatest and most valiant of the Syrian Isma’ili da’is of the thirteenth century A.C.
