Two men proposed to me at almost the same time. How do I choose?

You have the right to weigh both calmly before answering either. Until you have answered, no proposal is binding. Start with the same measures for both: religious practice, conduct when angry, readiness to provide maintenance, and how he treats his family. Ask your wali or someone you trust to make enquiries of people who know each candidate. Then pray salat al-istikharah and consult your family. Once you have decided, tell the man not chosen quickly and tactfully, so he is not left waiting without certainty. See criteria for choosing a spouse.
