Put something in front while praying according to the height of a saddle's back .

The Prophet Muhammad ﷺ advised people to place an object in front of them when they pray. This object should be the same height as the back of a saddle. This is so that it serves as a barrier between the person and whatever is behind them, allowing them to focus on their prayer without any distractions. It also helps keep their posture straight and prevents them from bowing too low or leaning too far forward during prayer. By doing this, Muslims can ensure that they are properly engaging in their prayers and not letting anything else distract or disrupt their concentration.

The hadith also teaches us about humility and respect for God's commands; even though we may not understand why we have to do certain things, we should still follow His instructions out of obedience and faithfulness. Additionally, it encourages us to take our worship seriously by ensuring that our physical posture reflects our spiritual attitude towards prayer - one of reverence and submission before God Almighty.
