What advice did the Prophet Muhammad (saw) give to Abu Huraira when he was unsure if he would be able to afford to marry?
      Narrated Abu Huraira:                          I said, "O Allah's Apostle! I am a young man and I am afraid that I      may commit illegal sexual intercourse and I cannot afford to marry."      He kept silent, and then repeated my question once again, but he kept      silent. I said the same (for the third time) and he remained silent.      Then repeated my question (for the fourth time), and only then the      Prophet said, "O Abu Huraira! The pen has dried after writing what you     are going to confront. So (it does not matter whether you) get      yourself castrated or not."
