Masa’il of Sitting on a Chair to Pray Salah

1. If a person is ill or excused (mazoor) to the extent that he is unable to pray his full salah standing up with complete ruku and sujood, then he should stand up for the duration or for the number of rakats he has the power and strength to do so. Thereafter, when is unable to stand up, he should complete his salah sitting down with ruku and sujood
2. If an ill person or excused person is such that he doesn’t have the strength to pray salah standing up, however, he is able to pray salah sitting down with complete ruku and sujood, then it is necessary for him to pray his salah sitting down on the ground with complete ruku and sujood. If such person prayed his salah on a chair, then his salah will be invalid because he is able to perform sujood completely, but on the chair, he will be missing it out and sajdah is a fardh act; salah is invalid by missing out a fardh act.
3. If an ill or excused person is such who is unable to perform sujood on the ground, however, he is able to pray his salah sitting down on the ground, the ruling for such person is that he will pray salah sitting down on the ground and perform sajdah by gestures. Such a person has an option of praying salah on the chair. But it is more preferable for him to pray salah sitting down on the ground as this is much closer to show servitude and that is more rewarding.
4. The ill and excused person is such that he cannot pray his salah sitting down on the ground, so then it is permissible for him to pray the full salah on a chair.
