Directing the soldiers on the southern border

Question:
Hello, yes, yes. I have four questions. Please, the first question is about those on the southern border who delay the prayer; is that permissible, O Shaykh? Now, the second question. The intoxicant or the smoker. Is it permissible to pray while intoxicated or smoking? Now, the third question. I am unable to fast for six months every year, because it is always a dead period. Now, the fourth question. I postpone it to the new year; is that permissible? That is, I fast for the missed days and fast for the new year. And the fourth question. The fourth matter is that this is a personal loan. Yes. It takes interest and profits from me; is this lawful or riba (usury or interest)? Now, thank you, O Abd al-Rahman. Thank you. May Allah bless you. In his first question, he says: Our brave soldiers, the protectors of the homeland and the protectors of this religion, O Shaykh, we pray for them. How do you direct them? May you be rewarded.

Answer:
Direct them to patience and seeking reward from Allah. They are upon a great reward, and they are at the frontiers of the Muslims. They are among those who stand guard in the path of Allah, Mighty and Majestic. Standing guard has a great virtue. So they are upon good if their intentions are sound and they preserve their religion. They are upon a great good. Yes.
