Nikaah & Marriage Issues

Waking the small baby from his nap

Q: My baby is almost a year old. He changed his nap times and now naps for the second time around 5 or 6pm. However, if it's getting close to 7pm, I wake him up as he only sleeps 3 or 4 hours post his wake up time and if he sleeps later than 7pm, he will sleep around 11 or 11:30pm at night. 

My mom says Islamically it is wrong to wake a sleeping baby. What is the ruling regarding this?

Using Sassa government grant amounts received on one's children

Q: I earn a decent amount of salary to take care of all the basic necessities of myself, my wife and 3 kids. At the end of the month I don't have any money to save for extra expenses. My wife is at home and does not work.

We applied for a sassa child grant for all my kids after they were born. We put aside that money for each of them every month separately. Alhamdulillah these savings have accumulated. 

My son and daughter both need myobrace treatment as their jaws are not fully developed and their teeth are not growing straight. Can we use their sassa savings to go ahead with the myobrace treatment as I don't have money to pay for this treatment for them? The cost for each child will be approx R12k.

Making a temporary nikaah

Q: If a person takes permission from a Christian prostitute to perform nikaah with her, will the nikaah be valid if he then performs the nikaah in the presence of two male Muslim witnesses. 

I fully understand that a person should not be doing this. I want to know whether the nikaah will be valid or not, not whether it is permissible to do so or not or whether one should do so or not. The result of the nikaah being valid is that a person will not be committing zina.

Chatting with one's potential spouse before nikaah

Q: Some things are decreed by Allah in which a person has no choice like death and the time of death, but in the case of marriage, a person has a choice in whom he/she chooses as a spouse. Since the person we choose to marry is one of the things which is not predestined/not predetermined by Allah (not to be confused with unknown to Allah for He certainly knows who we will choose with our free will), why are we limiting ourselves by not engaging and chatting to non-mahrams within limits? 

I would have definitely not met and subsequently not married my now spouse had we not engaged and chatted to each other. So since the person we marry is not influenced by Allah and is 100% all down to our choosing, why can't we date and interact with people with the intention of nikaah? This is certainly taking means and not being passive.
