Simply put, pulsars are rotating neutron stars. And pulsars pulse because they rotate! Pulsars pulse because the rotation of the neutron star causes the radiation generated within the magnetic field to sweep in and out of our line of sight with a regular period.

Pulsars have jets of particles moving almost at the speed of light streaming out above their magnetic poles. These jets produce very powerful beams of light. We see pulsars turn on and off as the beam sweeps over the Earth. Neutron stars for which we see such pulses are called "pulsars", indicating that the source of energy is the rotation of the neutron star.

Pulsars are highlymagnetized rotating neutron stars which emit a beam of detectable electromagnetic radiation in the form of radio waves,that sweep through the earth's line of sight.

1- والسماءِِ والطا رقِِِ ِ
قسم ہے آسمان اور اندهيرے ميں روشن هونے والے كى-
By the heavens and The Knocker.
2-وما ادرك ماالطارقِِِ
تجھے معلوم بهى ہے کہ رات كو نمودار هونے والى چیز كيا ہے-
How will you comprehend what the The Knocker is?
3-النجمُ الثاقب
وه روشن ستاره ہے -
It’s a piercing star. 86-The Knocker, 1-3
(آيت 3-1 سورة طارق پاره 30 )
The word “Tariq” طا رقِِ stems from the root “TaRaQa” طا رق meaning “knocking, striking.” In many translations of the Quran this word was taken for a name and left untranslated. The word may also mean “to pulsate” like a beating heart, from which the word “pulsar” is derived, denoting an object that is far away in space, and like a star produces a regular radio signal.
