Nikaah & Marriage Issues

Performing a Secret nikaah and thereafter re-performing the nikaah

Q: My daughter received a wedding proposal. We have accepted, but the problem is the boy can only marry her when he has completed his studies [1 year's time]. The kids want to see one another. Can we have a contractual nikkah now, no hankie pankie, but just spend time in parents presence, then when he can earn a living have another nikkah and they can now live as man and wife Insha Allah. What can you advise mufti. We don't want the kids to do zinnah/fitna and we understand that the boy wants to finish his studies, both sides of the parents can't afford to maintain the new couple now. Please advise.

Marrying one's cousin

Q: I have two uncles. My grandmother has breastfed my elder uncle's first child. Now my parents want me to marry younger uncle's daughter. So, is it permissible according to Islam as my grandmother has breastfed my eldest uncle's first child.
