Seeing blood on one's finger after performing Salaah

Q: I wanted to ask that, I must have bled a little from my finger which I didn't know about. I saw it after I put clean clothes away and it seemed dry. I don't know if this blood touched my clothes that I was wearing or the clean clothes I put away or anything I my have touched and with most clothes being black it's hard to tell.

1. Please can you tell me if I need to wash the clothes again or would they be considered pure?

2. Is my namaz counted in the same clothes I was wearing? 

Foregoing one's place in the first saff for a senior

Q: It has been observed in madaaris, khanqaas, marakis and masaajid in general that students, mureeds, mamoors and general musallies at the time of iqaamat forego their place of the front saff by stepping backward into the second saff to give preference to the ustaad, shaikh, ameer or another Muslim in general, to take their place in the front saff. At times these individuals are in the saff well before hand. On the other hand the one given preference comes much later or even a short while before salaah. Can Mufti Sahib please explain if it is correct to do this? Can one forgo one's reward for another? Please shed any other information you have on this subject.
