Ayat 56, Surat A'araf Considered.

[Abu Hafsat]

As-Salaam alaikum, 

  "INNA RAHMATALLAHI QARIBUN MINAL-MUHSININ.. Truly, the Mercy of Allah is near those who do good" (7:56)

Here, qaribun is not put in the feminine (qaribatun) although 'rahma' is feminine, because in reality that rahma is the Prophet, Sallallahu alaihi Wasallam... as explained in the ayat "WAMA ARSALNAKA ILLA RAHMATAN LIL-ALAMIN.. And We did not send you (O Muhammad) except as a Mercy to the world's" (21:107)

"Say: In the bounty of Allah and in His Mercy : therein (alone) let them rejoice. It is better than what they hoard" (10:58)

As Sayyadina Ibn Abbas, may Allah be pleased with him, said: "The bounty of Allah is knowledge of Tawheed, and His Mercy is the Prophet, Sallallahu alaihi Wasallam.
