I prefer to check whenever I feel discharge release. However, discharge in general can be release throughout the day without any feeling. So I’m confused as what to do.
I’m afraid if I check before each prayer not
enough discharge would have developed and then when I check my kursuf it could be difficult for me to dechiper the colour of the discharge due to its small
amount and due to the poor lighting in my bathroom. (Once I saw discharge
whilst I was in the bathroom which looked completely clear, and I had decided
to check the colour properly in the room next door which has better lighting
and it turned out the discharge was actually yellow. It is risky going into
the room next door because there are always people coming in and out.)

I tend to check 3 times a day, or around the times I’m desperate to use the toilet.

Which method is the best concerning my situation?

*Also – during istihadah, I plan on checking my kursuf after each prayer begins. Is this ok?

Assalamu ‘Alaykum

I deemed this matter to be highly urgent as it has driven me to great distress such that I cannot continue on without finding a solution to it. I have started studying at university. I did my best in compiling a time table that permits the upholding of timely prayer, albeit the time windows are somewhat narrow. Only, there is a problem with my particular case, which is that I happen to experience unpredictable and unnoticable emission of impurity. The rate of this occurance is insufficient to be considered incontinent according to both the rulings of the consensus and the Malikis – it simply does not occur often enough. But that is only worse for me because I find no way to clean myself of this impurity when I am not at home because it is mostly dry thus mere Istijmar with tissues will not suffice. In addition I have a heavy visual deficiency which makes it difficult for me to find my way in unfamiliar areas such as public bathrooms in mosques.

As previously noted, my window of opportunity for praying is present but slim. What if, while praying, I was to notice some emission such that my prayer would be invalidated. Not only could I not remove it, but it would also take time to repeat wudhu and prayer – time I do not always have. Then what if this happens during Jumu’ah when there is only one chance.

Whether I notice something or not, I know from experience that there almost always is some impurity present which I highly suspect is due to some medical condition. The point is, that it would be unrealistic for me to assume that there is nothing there simply because I felt nothing – that is only too rarely the case.

So to sum up, the problem is that:
1.) I almost cerainly have some impurity when going to pray when away from home.
2.) There is a small chance that during my prayer some impurity may come, out invalidating it.
3.) I find it almost impossible to clean it when not at home unless maybe with tissues, but again:
a) I take time due to my poor vision.
b) The impurity is mostly dry.

The last thing I want is to be unjustifiably deemed as excused because this impurity, although unpredictable, does not keep coming out for at least half the prayer time, which is the Maliki requirement and that is considered the easiest ruling. But at the same time, this matter seems difficult and it is often stated that there should not be any hardship in religion and that it is easy.

Should I instead abandon or change my studies and go home to perform propper Istinja? Or can the presence of impurity be tolerated under these circumstances?
