What is the ruling on greeting with a handshake and kissing among women inside the mosque while they are learning the Holy Quran?

A Muslim greeting his Muslim brother upon meeting is a Sunnah. As for embracing and kissing, the difference of opinion concerning them has been previously explained in detail when the gender is the same (men with men or women with women). This difference of opinion applies in normal, natural circumstances and without any feeling of an unnatural inclination. However, if there is an inclination or lust, then it is obligatory to avoid that.
