After passing urine or stool will it suffice to do istinja with only tissue paper or water?
I tend to use both, however sometimes at toilets there are only one of the two items available.

As you already normally do, it is best to use both water and toilet paper (i.e. a dry object). After this, the second-best option is to use water only. If not available, then you may use toilet paper only, but the Ḥanafī position is that you may only do this if the amount of najāsah (filth) being cleaned is small. If the amount of urine left on the body is estimated to be greater than the inner palm of your hand (approximately 6 cm), or the amount of stool is greater than a mithqāl (5 grams), then the toilet paper alone is considered insufficient, and water is required.
