Its not a wise idea at all. the 2 year wait I mean.
You will not only compromise your level of taqwa by possibly remaining in some sort of contact or forming some sort of relationship but will also mess with your mind and heart. Its not worth it and its the lure of Shayaan.
The beauty of marriage is in the fact that it is made halaal for you and is halaal in the eyes of Allah (swt). If you cannot make nikkah now and its something that doesnt look likely in the very near future then please- save yourself from hurt, from distress, from mental and emotional turmoil and more importantly Allah (swt)'s displeasure
Shatyaan deceives us and makes something look so good to us when in reality we KNOW its not good for us at all, how can it be if it troubles us so much and occupies our mind to the extent that we are probably being neglectful of Allah (swt)? IM not suggesting we are robots and dont have feelings etc- we do. But we also have control over WHAT WE CAN DO!
Allah has promise us a truth, promised us something good. If this is decreed for you and it is what Allah wants for you then nothing in this entire universe can stop it from happening (when its meant to happen). In the meantime, dont let shaytaan lure you, trap you, destroy and taint something which Allah (swt) has made so beautiful.
And Satan will say when the matter is decided: "It was Allah Who gave you a promise of Truth: I too promised, but I failed in my promise to you. I had no authority over you except to call you but ye listened to me: then reproach not me, but reproach your own souls. I cannot listen to your cries, nor can ye listen to mine. I reject your former act in associating me with Allah. For wrong-doers there must be a grievous penalty."
(surah Ibrahim, Ayah 22)
Its a fave of mine. Its talking about something else I think but for some reason, as an ayah on its own- it means so much to me. Hope it helps.
