Talking over internet with girls

Answer

Wa’alaykum as Salam wa rahmatullahi wa barakatuhu,

Speaking to non Mahram (strange) females over the internet is Haram. 

In a narration of Sahih Ibn Hibbaan, the Prophet (sallallahu alayhi wa sallam) said,

الْعَيْنَانِ تَزْنِيَانِ، وَاللِّسَانُ يَزْنِي، وَالْيَدَانِ تَزْنِيَانِ، وَالرِّجْلَانِ تَزْنِيَانِ، وَيُحَقِّقُ ذلك الفرج أو يكذبه   (صحيح ابن حبان – (10/ 267) 

“The eyes commit adultery, the tongue commits adultery, hands commit adultery, legs commit adultery and the private parts will either commit [the actual act of] adultery or it will not commit it.” (Sahih-Ibn-Hibbān 10/267)

Especially during the month of Ramadhaan, one needs to be more conscious not to disobey Allah. During these last few hours of Ramadhan, make a firm resolution to break off all contact with those girls.

By ejaculating, your fast has broken, and you need to keep one fast to make up for it.
