Is it permissible for a Muslim in this time to say: "I wish I were with the Companions of the Messenger of Allah, fighting alongside them?"

Question:
May Allah reward you, Honorable Shaykh. This questioner says: When we read about the virtues of the Companions (may Allah be pleased with them), and about their jihad, their asceticism, and the strength of their faith, we say, "Oh, if only we were with them," or "Oh, if only we had fought with them alongside the Prophet (peace and blessings be upon him)." Is this statement correct? And is this wish permissible?

Answer:
No, this is not appropriate. It is not appropriate for you to wish to be with them, because you might be with them and not have patience. You do not know; perhaps you will not have patience. There were people who were with them but did not have patience; they remained and became hypocrites, may Allah protect us from that. So you do not know. But it is sufficient for you that you love them, are pleased with them, seek forgiveness for them, and follow them. This is sufficient from you regarding their rights. And you defend their honor. This is sufficient from you.
