Issue 1001...
Issue 1001: * It is Wajib for a man to recite Surah al-Hamd and the other Surah loudly, while offering Fajr, Maghrib and Isha prayers, and it is Wajib for a man and a woman to recite Surah al-Hamd and the other Surah silently while offering Zuhr and Asr prayers. Issue 1002: * As a precaution, men must take care to recite loudly every word of Surah al-Hamd and the other Surah, including their last letters, in the prayers of Fajr, Maghrib and Isha.
Issue 1003: * A woman can recite Surah al-Hamd and other Surah in Fajr, Maghrib and Isha prayers loudly or silently. But, if a na-Mahram hears her voice, she should, on the basis of precaution, recite them silently, especially if allowing him to listen is haraam. Issue 1004: * If a person intentionally prays loudly where he should pray silently, and vice versa, his prayer is void. But, if, he does so owing to forgetfulness, or not knowing the rule, his prayer is in order.
And if he realises that he is doing a mistake while reciting the Surah al-Hamd and the other Surah, it is not necessary to recite again what he has recited not following the rule. Issue 1005: If a person raises his voice unusually high while reciting Surah al-Hamd and Surah, as if he were shouting, his prayer will be void.
Issue 1006: * A person should learn Surahs to be recited in Salat , so that he may not recite them incorrectly, and if one cannot by any means learn the whole of Surah al-Hamd, he should learn as much of it as he can and recite; but if that is a very small part, then as an obligatory precaution, he should add to it as many verses of Qur'an that he can remember. And if he cannot do that, he should add some Tasbeeh to it.
But if someone cannot recite Surah al-Hamd at all, then there is no necessary replacement for it. The recommended precaution for him is to join Salat al-Jamaat. Issue 1007: * If a person does not know Surah al-Hamd well, but can learn it, he should do so if the time of Salat permits. And if the time does not permit, he should act as guided in the above rule, and his prayers will be valid. But wherever possible, such a person should join Salat al-Jamaat to relieve himself of the responsibility.
Issue 1008: * To take wages for teaching obligatory acts of prayers is haraam, as a precaution, and taking wages for teaching Mustahab things is permissible.
