The word, "love," appears in 58 verses in the Quran.  However, the words "fear" and "terror" appear 101 times, almost twice as much frequently as the word, "love."
Let us explore this matter in greater detail.  Very, very often the verses with the word, "fear," exhort the believers to "fear Allah."  ALAS, THE WORD-COUNTER WEBSITE FREQUENTLY USES "OBSERVE" INSTEAD OF "FEAR."  SECOND PROBLEM:  sometimes "wives" is translated as "spouses" by the word count website.

The word "sinner" appears in the Quran in just eight verses; however, the word "disbeliever" appears in 176 verses!  Clearly, warnings about becoming one who disbelieves are far more prominent than those pertaining to sinful behavior.
​Who are disbelievers?  They are the people who refuse to believe the messages of the "Messenger of Allah" and other prophets.
Rarely is punishment prescribed by Allah given for sinning.  In Quran 2:81, we read:  "Yes, whoever earns evil and his sin has encompassed him - those are the companions of the Fire; they will abide therein eternally." and in Quran 2:206 we read: " And when it is said to him, "Fear Allah," pride in the sin takes hold of him. Sufficient for him is Hellfire."  In sharp contrast, very often when "disbeliever" is mentioned, the punishment that Allah intends to inflict on those who simply refuse to believe Muhammad -- namely, burning in Hell -- is also mentioned.

Strikingly, Quran 98:6  tells us that the worst of created beings in Islam are not those who sin, but those who refuse to believe Muhammad (the disbelievers)
Debate Question:  Why are disbelievers and not sinners the worst of created beings?  Could it be because Muhammad hated those who refused to believe him, so he had the god of his imagination hate these people too?

 To obtain counts of how many times particular words appear in the Quran, or how many Quranic verses have that particular word, we shall be using the webpage, ​www.masjidtucson.org/quran/wordCount/QuranWordCount.php .  From this webpage we find that the word "daughter" or "daughters" appear in 24 different verses.  The words "son" or "sons" appear in 159 verses.  Debate Question:  "Why does the Allah of Islam prefer to spend far more time talking about sons rather than daughters?
