Salaah

Sutra of the Imaam

Q: I know that the sutra of the imam is counted as the sutra for the followers, making it ok to pass in between the rows of the followers. But what if the imam has no sutra, will it then be impermissible to walk in between the rows of the followers?

How should a person suffering from Parkinson's disease perform Salaah?

Q: I am a Parkinson's disease patient. Parkinson's disease is ageing of the brain before time. I am now at a stage where I am unable to go to masjid, I pray at home and it is not easy. I keep having problems concentrating. On the days that my condition worsens my lips hardly move as I end up doing tilaawat in my heart. I sometimes forget which position I am in, usually forget what I have prayed. Often go to sleep and forget which rakah I am on. I try my best  to repeat (sometimes until the end of salaat time) I feel helpless. Is my salaah valid? In the above situation could I perform my salaah lying down and how would I do this?

Performing one rakaat

Q: First rakat of ishaa I said 'Ar-Rahman Ar-Raheem' but then I don't know whether I said the ha or HA with 'Ar-Raheeem'. I chose to ignore it as a doubt. During Salah I made many mistakes and corrections in the essential aspects - then after completing the prayer [all four rakaats] I ended prayer and did two sujood uh sahw. I went downstairs to get a drink, came back up then I still had the niggling doubt about whether I said ha or HA in 'Ar-Raheem' so I thought like you know it hasn't been a long time since I made Salaam so I said takbir and performed 1 rakaat in replacement of the rakaat in which I doubted with the full tashahhud and exited prayer and did two prostrations of forgetfulness Now plz tell me is my prayer valid or not?
