Husband gone missing

Q: I need a dua to read. My husband is in another country and he was on a journey and he was on the phone text with me and half way his phone just
went off. It's been 8 days his phones are off and never reach his house in Afghanistan. Please give me something to read so I can find him or any news of his to come to me. I'm so worried Ya Allah help me and my kids and my husband.

Repenting for one's sins

Q: For repentance you need to feel guilty about the sin you committed. I don't feel guilty in my heart, can I verbally say that I feel guilty about the sin, would that be enough? I can say verbally "I regret doing the sin, I shouldn't have done the sin" would that be enough?
