When your relationship with Allah ﷻ becomes a relationship of love, you will cry missing Him, especially when you see or visit His ﷻ house. You will cry and feel regret when you notice a shift in your relationship with Him. Remember, whoever loves to meet Allah ﷻ, Allah ﷻ loves to meet him/her. If you love to meet Allah ﷻ, Allah ﷻ loves to meet you too.
