Translation:

69. And those who strive in Our (Cause) We will certainly guide them to Our Paths: for verily Allah is with those who do right.

Notes (Tafseer)

3502. "Strive in Our Cause." All that man can do is to strive in Allah's Cause. As soon as he strives with might and main, with constancy and determination, the Light and Mercy of Allah come to meet him. They cure his defects and shortcomings. They provide him with the means by which he can raise himself above himself. They point out the Way, and all the Paths leading up to it. See next note.

3503. The Way of Allah (sirat-ul-Mustaqim) is a Straight Way. But men have strayed from it in all directions. And there are numerous Paths by which they can get back to the Right Way, the way in which the purity of their own nature, and the Will and Mercy of Allah require them to Walk. All these numerous Paths become open to them if once they give their hearts in keeping to Allah and work in right Endeavour (Jihad) with all their mind and soul and resources. Thus will they get out of the Spider's web of this frail world and attain to eternal Bliss in the fulfillment of their true Destiny.
