دعوتِ ذوالعشیرہ وہ واقعہ ہے جب نبی کریم ﷺ نے اپنے قریبی رشتہ داروں (عشیرہ) کو کھانے پر بلایا۔

اس دعوت کا مقصد ان کو اسلام کی دعوت دینا تھا، جیسا کہ اللہ تعالیٰ نے سورۃ الشعراء میں فرمایا: "وَأَنذِرْ عَشِيرَتَكَ الْأَقْرَبِينَ"۔

He was born in Umarkot (Sindh) in 1542.

He became Emperor in 1556.

Explanation

The sum of the internal angles of a polygon can be found using the formula:

(n-2) × 180°

where n is the number of sides.

For a regular octagon (8 sides):

(8-2) × 180° = 6 × 180° = 1080°

Since it's a regular octagon, all internal angles are equal. To find the measure of each internal angle, divide the total sum by the number of angles:

1080° ÷ 8 = 135°

Explanation

• Isotopes of an element have the same atomic number (number of protons).
• It means they have the same chemical properties and are considered the same element.

Explanation

A thinner convex lens has a longer focal length because it bends light rays less sharply than a thicker convex lens.

A thicker convex lens has a shorter focal length as it bends light rays more strongly, bringing them to focus sooner.
