The most sound view is that prayer in congregation in the mosque is obligatory and this is what is indicated by the Shar`i evidences detailed below.

The time of Duha prayer is from the time when the sun has risen to a certain height, until just before the time for Zhuhr prayer.

Several versions of the adhan have been narrated in sound reports from the Prophet (peace and blessings of Allah be upon him). It is Sunnah to use all the versions that have been narrated from him in order to revive the Sunnah and to put an end to disputes and differences.

Whoever is unable to pronounce al-Fatihah properly because of some defect in his tongue or because he is not an Arabic-speaker must learn to correct his pronunciation as much as he can. If he cannot, then he is relieved of this obligation.

This is how to calculate zakah on salary: If you take your salary for Muharram, and save one thousand Riyals of it, then you do likewise in Safar and the remaining months, when Muharram comes in the following year, you look at all that you have and pay zakah based on that.

The times of the prayers were mentioned by the Prophet (peace and blessings of Allah be upon him) in the hadith: “The time for Zhuhr is from when the sun has passed its zenith and a man’s shadow is equal in length to his height, until the time for ‘Asr comes. The time for ‘Asr lasts until the sun turns yellow. The time for Maghrib lasts until the twilight has faded. The time for ‘Isha’ lasts until midnight. The time for Subh (Fajr) prayer lasts from the beginning of the pre-dawn so long as the sun has not yet started to rise. When the sun starts to rise then stop praying, for it rises between the two horns of the Shaytan.”
