Issue No.1007- He who falls asleep unwillingly (e.g., falls asleep while performing sajdah) then wakes up during sajdah and doubts whether he is in the sajdah of the prayer or the prostration of thankfulness after the prayer, should repeat the prayer.
Issue No.1013- Talking by mistake or forgetfully does not invalidate the prayer.
Issue No.1014- If one utters a meaningful word consisting of one single letter, (like 'Qi' in Arabic which means 'secure') while intending its meaning the prayer would be void. If one does not intend its meaning though and is aware of the meaning, he should, as an obligatory precaution, perform prayer again.
Issue No.1019- It is obligatory to answer another’s Salām even though one is offering prayer. Saying Salām is recommended and one should reply to it in a way that it may be counted as the reply to Salām. That is to say, if he delays the reply so much that it may not regarded the reply to that Salām, then he has committed a haram act; it would no longer be obligatory to reply to it though.
Issue No.1020- If a person in prayer does not respond to Salām, his prayer is correct, though he has committed a sin.
Issue No.1021- It is obligatory to reply to a Salām in a way that one who greeted him can hear it. However, if he who says Salām is deaf or he is in a place where there is a lot of noise it would suffice if the greeted person replies in the usual way, and as a recommended precaution, he should also reply to his Salām by indication.
Issue No.1022- It is obligatory that a person, who is in prayer, responds to Salām with the intention of replying to Salām, not with the intention of reciting some verses of the holy Qur’an, etc.
Issue No.1025- If a person enters a place and says Salām to a group of people present there, it is obligatory upon all to reply. However, if one of them replies, it is sufficient.
Issue No.1026- If a person says Salām to a group of people among whom some are offering prayer, and one praying doubts whether the Salām was intended for him or not, it will not be necessary for him to reply in return. Similarly, if he is sure that the one who had greeted intended him as well, then he should reply, unless someone else already responded.
Issue No.1027- It is a highly recommended act to greet with Salām, and a great stress has been laid on this in the holy Qur’an and Islamic narrations. It is befitting that a riding person should greet one who is walking, and a person who is standing should greet one who is sitting, and a younger person should greet an elder.
Issue No.1028- If two persons simultaneously say Salām to each other, both should answer the Salām of the other as an obligatory precaution.
Issue No.1029- It is obligatory for a praying individual to answer the greetings and salutations of others while offering prayer even if they greet him in a foreign language. Therefore, if the individual who has greeted speaks Arabic, the praying person should greet them back in Arabic; otherwise one must greet them back in their own language.
