O son, I'd be lying if I say I love you for how can I love you when Allah loves you more than I do, so know that I love you not. I'd also be lying if I say I love you when Allah loves you 70 times more than I do.
When you are thirsty and in need of food or drink, do not ask from me, ask Him first, say "O Allah, I need some milk', then ask for it from your mother. It is He who makes me be thoughtful and caring towards you. I will thus bring what you need for you. So, be reliant on Allah, not on me, for He is the ultimate Provider.
Be like Zainab, the daughter of Saidina Ali. She asked her father, 'O father, do you love us?' Ali said, 'Of course I do!' Zainab said, 'How can you love us and love Allah in the same heart? How about you love Allah in your heart and you take care of us.'
Zainab is certainly right for "Allah has not made for any man two hearts inside his body...' (Al-Ahzab, 4).
O son, the only other love you are allowed to have in your heart is the love for Rasulullah s.a.w. And know that I will only consider you my son after you have dreamed of Rasulullah s.a.w.
To achieve that you must do salawat as many times as you can. 'Dala'il Khairat' is the key. Learn it by heart and recite it daily. It is the best inheritance a mother could give a son and it is the only inheritance a son needs.
Still after you have dreamed of the Prophet, I might not yet consider you my son until you tell me you have seen Rasulullah s.a.w in person. To achieve that you must continue making a lot more salawat. Once you have done that and become successful, I will know that you are ready for anything and you will have become my true son.
This is what you must learn to do and achieve. This is the training given to the children of the salafus soleh and I am sure you want to be like them too. The Prophet s.a.w has said that 'one is not considered a Mukmin until one loves Rasulullah more than he loves his parents, his children or anyone else.' The Prophet also said that, 'None of you will believe until I am dearer to him than his own soul.'
O son, when you have grown to be a true son and a true Mukmin, you will understand why I cannot say I love you and in that very same understanding you will come to realize how much I care about you!
