@Maddie271 Does the pot your Ficus benghalensis is in have a drain hole? If no, you should know it's difficult to keep a plant healthy for extended periods unless you can flush the soil to: A) prevent accumulation of dissolved solids (salts) in the soil solution; this, because a high level of dissolved solids limits water and nutrient uptake, B) to prevent the ratio of nutrients, each to the others, from becoming badly skewed. An excess of any one nutrient can limit uptake of one or more of the other nutrients essential to normal growth. Example: A high level of phosphorous in the grow medium can limit uptake of calcium, potassium, copper, zinc, and especially iron.
If you're making use of a collection saucers and flushing the soil as you water, the next logical concern would be whether or not you're over-watering. How do you determine when it's time to water?
How long have you had the plant?
By any chance, has the plant been moved indoors recently, or to a spot indoors with less light? A change in light levels, especially a sudden decrease in light intensity or duration, can force the plant to begin the process of shedding leaves unable to create enough food/energy (via photosynthesis) to justify continued retention. Too, foliage higher on the tree can shade older foliage lower on the tree and force onset of the shedding process.
What are you doing about fertilizing? Fertilizing is an essential part of growing nearly all plants maintained in containers. If you're watering correctly, i.e., if you're flushing the soil as you water, you should fertilize about every 3rd-4th watering in summer and every 4th or 5th watering during the darker months (mid-Sep through mid-May).
It would be nice to see a full image of the entire plant and pot.
