Similarly, if oneoffering prayer in a sitting posture becomes capable of standing, he should offer, while standing, that part of the prayer which he can. However, he must stop reciting until his body becomes still.
Issue No.893- If a person considers it probable that at the end of the prescribed time he will be able to offer prayer standing, he should not offer prayer earlier, as an obligatory precaution.
Issue No.894- If standing is possible, but he knows, or there is a reasonable possibility, that standing would be harmful for him, or that his illness will prolong (for example, his wound, or the fracture of his bone will take longer to heal), he should perform prayer in sitting posture and in case sitting is harmful also, he should offer the prayer in a lying posture.
Issue No.895- It is befitting that the person offering prayer stands straight, slackens down his shoulders, places his hands on his thighs, joins his fingers together, places the weight of his body equally on two feet, looks at the place of sajdah and stands in humility. It is better for men to keep an open space between their feet while standing and for women to keep the feet joined.
Issue No.933- If at the time of uttering the obligatory dhikr of rukū‘, someone shoves him or he loses stillness due to any other reason, he should repeat the dhikr after his body becomes still. However, there is no harm in minor motions.
Issue No.935- If a person intentionally raises his head from rukū‘ before the completion of the obligatory dhikr, his prayer is void. In case, however, he raises his head by mistake and before he exits the state of rukū‘ he recollects that he has not completed the dhikr of rukū‘, he should make himself still and utter the dhikr. And if he recollects it after he has exited the state of rukū‘, his prayer is correct.
Issue No.934- If a person recites the dhikr of rukū‘ before he has properly bowed down and before his body becomes still, he should repeat it after his body becomes still. If he does so intentionally, he should, as an obligatory precaution, offer the prayers later again.
Issue No.938- If a person’s back is bent due to old age or diseases or other reasons he should, at the time of performing prayer, straighten himself as much as possible, and if he is not able to do so, he should straighten himself a little before rukū‘ and then come back to the state of rukū‘, and if this is not possible either, he should bow a little more for rukū‘ provided that he does not exit the state of rukū‘. And if that is also not possible, he should, as an obligatory precaution, make an indication with his head for rukū‘ and also consider that state of his to be a part of rukū‘.
Issue No.940- It is obligatory to stand straight after the completion of rukū‘, and after the body has become still, one should go to sajdah. And if one abandons this intentionally, his prayer will be void, but if it is abandoned unintentionally there will be no problem in it.
Issue No.949- While in sajdah, if one is not uttering the dhikr, he can lift or move some of the seven limbs of sajdah, other than the forehead, and then place them back again, but this is not permitted while uttering the dhikr.
Issue No.950- After the first sajdah, one should sit up until the body becomes still, and then perform sajdah again.
Issue No.952- When a person places his forehead, by mistake, on a place that is higher or lower than four joined fingers compared to the place where his knees and toes rest, if it is so high that it could not be called a sajdah, he should raise his head and place it on a point whose height is less than four joined fingers. But, if the height is to the extent that it is still called a sajdah, it is obligatory to drag his forehead [while connected to the ground], to a place which is equal to four joined fingers or less [in height]. If this is not possible, the obligatory precaution is that he should complete his prayer and reoffer it.
