Allah is God, the All-powerful, He does not require any help. Healing depends on whether the sick asks for healing. As for resurrection, all human beings will be resurrected once we are dead.

Allah only has the ability to heal or resurrect when he combines his powers with the powers of the super-best-friends; (Buddha, Jesus, Joseph Smith, Krishna, Lao Tzu, Moses, Muhammad and Sea Man)

Replace the name "Allah" with "God," and you still have the same question.

Has anyone ever come back from the dead.....? & dont they tend to eat brains more than heal?

No he has not. Jesus is the only one who has healed. I have been healed in Jesus name on my neck from injury in car accident. I have been healed praying to Jesus for arthritis in my knees totally healed. I have prayed for others a friend with tumor in leg and in Jesus name totally healed the Dr. was amazed and said yes, it must be your Jesus. Many miracles I have seen and the bible says lay hands on the sick and they shall recover. Thanks for your question another time to Glorify Jesus Christ.

Allah is the Healer and there is No healer but Him. Allah is the Resurrecter and there is No resurrecter but Him. [80] "And when I am ill, it is He (Allah) who cures me. [81] "And Who will cause me to die, and then will bring me to life (again). [The Noble Quran 26:80-81] ================= Allah, The Healer: [83] And (remember) Ayyub (Job), when he cried to his Lord (Allah): "Verily, distress/illness has seized me, and You are the Most Merciful of all those who show mercy." [84] So We (Allah) answered his call, and We removed the distress (illness) that was on him, and We restored his family to him (that he had lost) and the like thereof along with them, as a mercy from Ourselves and a Reminder for all those who worship Us." [The Noble Quran 21:83-84] "[41] And remember Our slave Ayyub (Job), when he invoked his Lord (saying): "Verily Shaitan (Satan) has touched me with distress (by ruining my health) and torment (by ruining my wealth)! [42] (Allah said to him): "Strike the ground with your foot: This is (a spring of) water to wash in, cool and a (refreshing) drink." [The Noble Quran 38:41-42] "[12] And when harm touches man, he invokes Us (Allah), lying down on his side, or sitting or standing. But when We (Allah) have removed his harm from him, he passes on his way as if he had never invoked Us for a harm that touched him! Thus it is made fair-seeming to the Musrifun that which they used to do." [The Noble Quran 38:12] "[107] And if Allah touches you with hurt, there is none who can remove it but He, and if He intends any good for you, there is none who can repel His Favor which He causes it to reach whomsoever of His slaves He wills. And He is the Oft-Forgiving, the Most Merciful." [The Noble Quran 10:107] "[62] Is not He (Allah) (better than your gods) Who responds to the distressed one, when he calls on Him, and Who removes the evil, and makes you inheritors of the earth, generations after generations? Is there any ilah (god) with Allah? Little is that you remember! " [The Noble Quran 27:62] "[38] And verily, if you ask them: "Who created the heavens and the earth?" Surely, they will say: "Allah (has created them)." Say: "Tell me then, the things that you invoke besides Allah - if Allah intended some harm for me, could they remove His harm? Or if He (Allah) intended some mercy for me, could they withhold His Mercy?" Say : "Sufficient for me is Allah; in Him those who trust (i.e. believers) must put their trust." [The Noble Quran 39:38] ============= Allah, The Resurrecter [259] Or like the one who passed by a town and it had tumbled over its roofs. He said: "Oh! How will Allah ever bring it to life after its death?" So Allah caused him to die for a hundred years, then raised him up (again). He said: "How long did you remain (dead)?" He (the man) said: "(Perhaps) I remained (dead) a day or part of a day". He said: "Nay, you have remained (dead) for a hundred years, look at your food and your drink, they show no change; and look at your donkey! And thus We (Allah) have made of you a sign for the people. Look at the bones, how We bring them together and clothe them with flesh". When this was clearly shown to him, he said, "I know (now) that Allah is Able to do all things." [260] And (remember) when Ibrahim (Abraham) said, "My Lord! Show me how You give life to the dead." He (Allah) said: "Do you not believe?" He (Ibrahim (Abraham)) said: "Yes (I believe), but to be stronger in Faith." He said: "Take four birds, then cause them to incline towards you (then slaughter them, cut them into pieces), and then put a portion of them on every hill, and call them, they will come to you in haste. And know that Allah is All-Mighty, All-Wise." [The Noble Quran 2:259-260] "[243] Did you (O Muhammad (peace be upon him)) not think of those who went forth from their homes in thousands, fearing death? Allah said to them, "Die". And then He restored them to life. Truly, Allah is full of Bounty to mankind, but most men thank not." [The Noble Quran 2:243]
