What are the consequences of lying and swearing a false oath upon the Qur'an in this particular situation?

The questioner must offer sincere repentance to Allah for committing a grave sin, which is swearing a false oath, especially one intensified by the Quran. He could have avoided this by using equivocation in his speech. He must also repent and seek forgiveness for the sin of looking at his neighbor and for harming neighbors, and strive against his lower self to avoid falling into desires, knowing that Allah is watching him, and that shyness from Allah is more befitting than shyness from people. Some scholars are of the opinion that expiation is obligatory for such an oath.
