What is the ruling on combining and shortening prayers, or shortening prayers only, for a traveler who moves about for three days, a week, or more or less? And what is the treatment for the tension, anxiety, sadness, fear, and nervousness associated with menstruation that affects social relationships?

It is permissible to shorten the four-rak'ah prayers (qasr) and to combine two prayers (jam') if the conditions are met. Qasr is a Sunnah, while jam' is merely permissible, and it is better to avoid it. Therefore, anyone who equates jam' with qasr is ignorant, because the Prophet differentiated between them. Scholars have agreed on the Sunnah status of qasr and differed on its obligatory nature, and they have debated the permissibility of jam'. It is better to avoid combining two prayers and to pray each prayer at its appointed time. If you undertake a permissible journey whose distance exceeds 83 kilometers and you have passed all the houses of the village, then qasr is Sunnah for you, and jam' is permissible, though it is better to avoid it.
